The self-driving car is no longer science fiction, it is already rolling on Swiss roads. Since 1 March 2025, Switzerland has had, with the Ordinance on Automated Driving (VAF)[1], a clear legal framework that for the first time expressly permits motorway pilots, driverless vehicles and automated parking. For once, the legislator was even faster than the industry; while the legal framework is in place, there are currently no series-production vehicles with an approved automation system on the market.

Regulation is developing rapidly not only in Switzerland but worldwide. EU directives, EU regulations and UNECE regulations are also binding on Switzerland. These international requirements ensure the technical harmonisation of road vehicles and promote road safety, environmental protection and the free movement of goods.

The following bodies of rules are particularly relevant for automated driving:

1. Regulation (EU) 2022/1426[1] (in conjunction with Regulation (EU) 2019/2144[2] and Delegated Regulation (EU) 2022/2236[3]) on the type-approval of the automated driving system (ADS) of fully automated vehicles;
2. the UNECE Regulations on cybersecurity (No. 155)[4], software updates (No. 156)[5], automated lane-keeping systems (No. 157)[6] and driver assistance systems (No. 171)[7]; and
3. the Vienna Convention of 8 November 1968 on Road Traffic (SR 0.741.10)[8], in particular on the question of whether a driver must be present.

For companies, investors, fleet operators and mobility service providers, this new legal framework opens up considerable opportunities, but also demanding legal questions. We answer five of them below.

When does a car actually drive «by itself»?

Not every vehicle with an assistance system is an automated vehicle. The internationally established SAE J3016 standard distinguishes six levels of automation, from Level 0 to Level 5:

Automated driving only begins at Level 3: vehicles that can take over the driving tasks permanently and comprehensively, at least under certain conditions. Only the highest level, Level 5, is truly «autonomous» in the literal sense; today's systems technically reach a maximum of Level 3.

In Switzerland, three specific use cases have been permitted since March 2025:

1. the motorway pilot: drivers may take their hands off the wheel on motorways, but must be able to intervene again at any time when prompted by the system;

2. automated parking without a driver present in car parks signposted for this purpose; and

3. the operation of driverless vehicles on routes approved by the authorities.

What approvals and technical requirements are needed?

Vehicles with an automation system must meet special requirements going beyond the general requirements in order to be admitted. Under the general requirements set out in Art. 3 VAF, the system must guide the vehicle in the longitudinal and lateral directions, be intuitively deactivatable at any time, have functions for accident avoidance as well as safeguards against unlawful third-party interference, and master all traffic scenarios in accordance with recognised international rules. During operation, the system must take over the operation of the vehicle continuously, comprehensively and reliably, comply with all relevant traffic rules, detect technical malfunctions and indicate the need for human intervention with a sufficient time reserve (Art. 3 paras. 2 and 3 VAF).

The driving-mode memory is central (Art. 7 VAF): automated vehicles must record certain events (such as emergency manoeuvres, collisions or technical malfunctions), together with data elements such as the type of event, time stamp and position. In addition, for the entire supported operating period, manufacturers must hold valid certificates from a national type-approval authority for the management systems for cybersecurity (UN Regulation No. 155), software updates (UN Regulation No. 156) and safety for driverless vehicles under Regulation (EU) 2022/1426 (Art. 8 VAF).

Switzerland's approach to type-approval is noteworthy (Art. 11 et seq. VAF): Switzerland currently refrains from having its own type-approval provisions and instead recognises the requirements of the EU and UNECE. Automated vehicles that are to be admitted here therefore require a foreign type-approval; ASTRA (the Federal Roads Office) merely carries out random conformity checks. Manufacturers and importers of driverless vehicles must report safety-relevant incidents to ASTRA, and ASTRA may declare new provisions applicable to vehicles that have already been admitted, for instance in the event of a hacking attack (Art. 6 VAF). Operation is thus strongly tied to approval and operating conditions: driverless vehicles require cantonally approved routes and must be supervised by operators from a control centre.

What happens to the recorded data?

Automated vehicles must be equipped with a driving-mode memory (colloquially a «black box») that records events such as the start and end of emergency manoeuvres, system failures, collisions, and the activation and deactivation of the automation system. The processing of this data is subject to strict conditions: under Art. 25g para. 3 SVG, the data may be read out and processed by the competent police, judicial and administrative authorities exclusively for the purpose of investigating accidents or assessing traffic-rule violations.

Manufacturers and importers of driverless vehicles and of vehicles with an automated parking system must report safety-relevant incidents to ASTRA and must agree with the vehicle keepers or the operators of approved parking areas on how the necessary information is to be obtained. Operators of car parks offering automated parking must also notify the police in the event of an accident. Data protection and controlled access to this driving data are therefore a central and legally sensitive building block of the new regime, especially for fleet operators and mobility providers that process large volumes of data.

Who is liable when the software steers?

If a person is harmed in an accident, in principle the insurer provides compensation first; only afterwards is it clarified who was actually responsible. The key point: despite technical autonomy, the vehicle keeper remains liable under the causal liability of Art. 58 SVG, a no-fault, risk-based liability. In an accident involving an automated vehicle, three levels of causation ultimately come into consideration:

1. the manufacturer (for instance in the case of software or sensor faults under the Product Liability Act);
2. the driver (if they were steering themselves at the time of the accident); or
3. the keeper (for example in the case of inadequate maintenance).

Legally, this is so intriguing because the allocation of risk shifts noticeably: from the driver to the system function, from the classic driving error to a product, software or maintenance defect, from pure SVG liability towards questions of recourse, product liability and evidence, and from the visible course of the accident towards the evaluation of technical data. Whether the human or the system was in control at the time of the accident can be traced through the driving-mode memory. The evaluation of this data thus becomes decisive for asserting recourse claims. For manufacturers, importers and operators this means a potentially higher liability risk; and for all parties involved, the urgent need to settle the contractual allocation of risk cleanly at an early stage.

What role does cybersecurity play?

A self-driving vehicle is essentially a rolling computer, and thus a potential target for cyberattacks. Cybersecurity is therefore not merely a peripheral technical issue, but a load-bearing element of the approval regime. Manufacturers must hold valid certificates for their cybersecurity management system under UN Regulation No. 155 and for their software-update management system under UN Regulation No. 156, and this for the entire supported operating period of the vehicle. The aim is to prevent external attacks and to avoid failures and malfunctions.

The regulation also takes account of this risk dynamically: ASTRA may even declare new provisions applicable retrospectively to vehicles that have already been approved and put into circulation, for example when certain vehicle types are affected by a hacking attack (Art. 6 VAF). For companies, this means: cybersecurity is not a one-off approval hurdle, but an ongoing legal and organisational obligation throughout the entire life cycle of the vehicle.

Conclusion

Self-driving vehicles will fundamentally change mobility, and in Switzerland they are already a reality. In Zurich's Furttal, the Swiss Transit Lab, the cantons of Zurich and Aargau and the SBB (Swiss Federal Railways) are deploying self-driving vehicles in the «iamo» pilot project (intelligent automated mobility); following approval by ASTRA, they are for the first time travelling in automated mode on public roads, and the public should be able to use the service in the first half of 2026[10]. Level 5 vehicles do not yet exist, but development is advancing quickly, and it is foreseeable that full automation will follow in the not-too-distant future.

Automated mobility is opening a new frontier of opportunity for investors, developers and operators, and with it a set of questions that deserve early attention: approvals and admission, liability and recourse risks, data access and data protection, and the allocation of risk between manufacturers, importers, operators and users. Addressing these questions early is what turns a promising technology into a sound, long-term investment.

On 29 June 2026, ETH Zurich and the Paul Scherrer Institute published a joint white paper by nineteen researchers across four independent energy-system models. Its message is clear: new nuclear becomes competitive in Switzerland once three conditions line up, the state backs nuclear alongside renewables, financing costs fall from roughly 8% to 5% through guarantees or contracts for difference, and construction costs move toward CHF 8,000 per kilowatt or below. The lower the build cost, the stronger the case: new nuclear pencils out in one of the four models even at CHF 12,000 per kilowatt, and in more of them as costs fall toward CHF 5,000.

That is the tension: Parliament made new plants possible while withholding the very support the study calls their precondition. Lifting the ban is right, but only half a decision. The five questions below set out what was decided, what was left out, and what still has to be settled before the vote.

A permit is not a power plant. Parliament legalized the building and, in the same breath, outlawed the one thing that would make it bankable.

1. What did Parliament actually decide, and what did it leave out?

On 18 June 2026 the National Council, following the Council of States, adopted the Federal Council's indirect counter-proposal to the “Blackout stoppen” initiative by 108 votes to 87, making new nuclear plants legally buildable for the first time in fifteen years. Concretely, the counter-proposal deletes Article 12a and Article 106 para. 1 bis of the Nuclear Energy Act (KEG), the provisions that since 2018 barred any general license for a new plant, and inserts a requirement that financing be secured in advance. On its face, this restores technology neutrality. But the parliamentary majority went further than mere permission: the National Council line rejects state support for new reactors and would grant a framework license only where the construction and operation of a plant are financially assured on private terms. In other words, the legislator has re-opened the door and, at the same time, removed the ramp that leads to it. The decision answers the question of legality. It leaves entirely open the question that actually governs whether a plant ever gets built: who carries the multi-decade financial risk, the very point the ETH study puts front and center.

2. What does the ETH study show, and where do we part ways?

The arithmetic is careful, and on its own terms it holds: new plants become competitive once the state supports them, financing costs fall from around 8% to 5%, and construction costs move toward CHF 8,000 per kilowatt. We accept that. But two features deserve emphasis. The analysis does not model small modular reactors as a technology in their own right. It represents nuclear through a single capital cost per kilowatt of installed capacity, and its most expensive case, CHF 12,000 per kilowatt, is taken from recent first-of-a-kind gigawatt projects in Europe and the United States. The authors themselves attribute those prices to being the first of their kind, and expect learning to bring costs toward CHF 8,000. The serial, factory-built logic of modular reactors is exactly the route to the lower costs at which the models turn positive, yet it lies outside them. And while it is right that Switzerland could reach net zero without new nuclear, leaning on hydropower and photovoltaics for roughly three quarters of supply, that path quietly accepts structural winter import dependence as its price. That is what we are not willing to accept. A high first-of-a-kind cost is an argument for a serious build program and a sound financing framework, not for treating nuclear as optional.

3. How much nuclear does Switzerland need to stay sovereign?

Enough to stay in control of its own winter supply. Demand is set to climb from about 57 terawatt-hours today to between 75 and 90 by 2050 as transport, heating and industry electrify, just as the existing reactors, some 23 terawatt-hours, reach the end of their lives. On a cold, windless winter night, solar and run-of-river hydro cannot cover that load, and the gap is filled by imports from neighbors whose own margins are shrinking. A firm domestic baseload of 25 to 30 terawatt-hours, roughly nuclear's share today carried into a larger system, would keep that capacity in Swiss hands instead of surrendering it to a market the country does not steer. Letting the fleet retire unreplaced does the opposite. That reactors are slow or costly to build is an argument about execution, not direction, and the technology answers part of it: the latest designs, including the small modular units now nearing deployment, are markedly safer than the plants they would replace, built around passive safety and a far smaller footprint. The wiser course is to treat that firm capacity as the strategic asset it is, a dependable foundation for the country's future supply.

4. Is there a lawful financing path, and should the state take it?

There is, and Switzerland has the legal tools to build it. A contract for difference, under which the state guarantees a fixed strike price and settles the gap either way, is the instrument the ETH authors point to, and it is precisely what the National Council line refuses. Introducing it would mean squaring it with the Electricity Supply Act (StromVG), the Energy Act (EnG) and the 2024 “Mantelerlass” on secure electricity supply from renewables, and treating it honestly as state aid. None of that is a barrier so much as a design task: the European Union already uses a contract for difference for new nuclear, at Hinkley Point C, which shows the instrument is workable rather than forbidden and gives Switzerland a template to negotiate around in its own electricity talks with Brussels. Behind the build cost sits the long tail, liability under the Nuclear Energy Liability Act and the decommissioning and waste-disposal fund, and a serious framework prices that in from the start. These are reasons to design the financing carefully. They are not reasons to leave the permission empty.

5. What should be decided now, in the window before February 2027?

The supply gap is real, and it widens as the economy electrifies: petrol cars give way to electric ones, oil and gas boilers to heat pumps, fossil-fueled industrial processes to electric ones, and digital infrastructure and data centers add load of their own. Without firm domestic baseload, Switzerland will meet that rising winter demand with imports, year after year. That is an argument for deciding seriously, not for deciding halfway. If the country wants the nuclear option to be genuine, it must legislate the financing architecture the ETH study itself identifies as the precondition: a defined risk-transfer mechanism, a bankable license framework, and a clear-eyed answer on state aid and the EU electricity file. What it should not do is what it has done so far: permit the plant, forbid the financing, and leave investors to reconcile the contradiction. Switzerland has made the easy half of the decision. The hard half is still on the table, and the months before the vote are the time to put it there.

Opponents, among them the Schweizerische Energiestiftung, the Social Democrats and the Greens, read the same study as proof that new nuclear is neither economic nor necessary, and want the repeal rejected at the ballot. We read it differently. A system in which net zero is technically reachable without nuclear is not the same as a supply that stays secure, sovereign and affordable in the depths of winter. Cost is a reason to structure the financing intelligently, not a reason to rule out a technology the country will need.

Our view

From a legal and economic perspective, repealing the new-build ban is only a first step, not yet a bankable investment framework. As long as the legislature does not create a financing architecture that investors can rely on, the planning certainty infrastructure investment requires is missing. Our position is clear, and it is not the study's: Switzerland needs new nuclear. Holding a firm domestic baseload on the order of 25 to 30 terawatt-hours, enough to keep roughly today's nuclear share as demand climbs toward 75 to 90 terawatt-hours by 2050, is what genuine energy sovereignty looks like, the difference between generating our own power and depending on imports we do not control. The latest reactor technology is markedly safer than the plants it would replace, and it belongs at the center of the country's energy infrastructure, not at its margin. Permission without financing is symbolism, not location policy. Switzerland should finish the decision it has started: commit the financing, build the capacity, and secure its own supply.

FuW opinion article by Dr. iur. Alexander Schiemenz, LINDEMANNLAW, July 2026

Switzerland is arguing over a housing shortage, and the Federal Council delivers an answer: a stricter Lex Koller. The consultation has been running since 15 April 2026 and ends on 15 July 2026. For the first time, listed real estate funds, SICAVs and real estate companies are to fall under the authorisation regime. It sounds like decisive action. Above all, it is symbolism. For the bill does not address the cause of the scarcity, but the capital market that helps finance housing construction, and it does so with an instrument that can hardly be enforced in exchange trading. The political trigger is well known: after the debate over the «10-million Switzerland», the Federal Council promised accompanying measures. This reform is one of them. The driver is the optics of the immigration debate, not evidence that foreign investors are driving up rents.

« A fund unit gives no one control over Swiss land. It provides a return, and lawmakers a bogus argument. »

1. What does the bill change legally, and why is it problematic to treat a fund unit like a piece of land?

The Lex Koller pursues a single declared purpose (Art. 1 BewG): to prevent the «foreign domination of domestic land». That is a question of control over land and soil. This is precisely where the preliminary draft shifts the line. In future, «acquisition» is also to include anyone who takes over units in real estate funds, shares in real estate SICAVs or interests in real estate companies with a controlling position (Art. 4 para. 1 lit. c, cbis, d and e VE-BewG). This reverses a proven status quo: since 1 March 2013, persons abroad have been able to freely acquire regularly traded fund units. The reason was obvious. A fund unit is not a piece of real estate. It provides a proportionate return, but no power of disposal over a specific plot, no voting right over letting, conversion or sale. Whoever holds an exchange-traded real estate fund «controls» as little land as the holder of a bond controls the company to which it lends money. The reform treats a capital investment like a purchase of real estate. That is not the closing of a loophole, but a confusion of categories.

2. Why can the new rule hardly be enforced in practice in exchange trading?

Even more serious is how the new rule is to be monitored. Enforcement intervenes directly in the capital market. Exchange participants and firms that trade listed securities over the counter would have to review every relevant order, clarify whether the buyer is a person abroad, and refuse execution without authorisation (Art. 19b VE-BewG). Fund documents would have to exclude non-authorised persons abroad from the outset (Art. 67a, 71a and 118j KAG). Violations cost up to 250,000 francs (Art. 28a VE-BewG). The problem is not good will, but the mechanics. Listed funds and SICAVs do not maintain an ongoing register of their beneficial owners. In split-second trading on the exchange, the beneficial owner is often only identifiable with a delay, but the bill demands seamless control. What is operationally unachievable leads to the only remaining solution: withdrawal from the exchange. The Confederation itself writes that a delisting is the likely result. Around 44 Swiss real estate funds with a volume of nearly 80 billion francs would be affected. A measure that destroys transparency and liquidity in order to feign control is not supervision. It is an own goal.

3. How does the Confederation itself assess the effectiveness of the measure, and what do the figures say?

The strongest argument against the reform comes from the Confederation. The commissioned regulatory impact assessment concludes that the measure is «not suitable» for easing the housing market and has only a «minimal» effect on foreign land ownership. The figures are clear. Foreign investors hold around 5.32 billion francs in listed Swiss real estate funds and SICAVs, of which 2.42 billion are in the residential segment. Against this stand 26.65 billion that Swiss pension funds alone invest in real estate abroad. Whoever speaks of «foreign domination» here confuses a marginal quantity with a structural problem.

4. What further risks does the Confederation identify, and what about constitutional proportionality?

The report further warns that sectoral capital controls generally do not work, that diverted capital could push domestic investors more strongly into the market, and that a signal of isolation could harm the location and trigger countermeasures against Swiss owners abroad. As early as 2017, a similar tightening was dropped after the consultation. Constitutionally, the fundamental question of proportionality remains (Art. 5 para. 2 BV): a measure that, according to official analysis, does not achieve its goal is not suitable, and therefore hardly justifiable.

5. What does this mean for investors, and how should they use the remaining window of time?

The housing shortage is real, and it deserves serious policy: more building land, faster procedures, denser construction. A stricter Lex Koller delivers none of this. It produces bureaucracy, drives liquid capital out of transparent vehicles and shifts the problem instead of solving it. Whoever wants to improve the reform should delete or narrowly frame the provisions on indirect investments and listed securities and address only genuine control over residential building land, equally for all non-residents. The consultation runs until 15 July 2026; the bill can hardly enter into force before 2028 in any case. Investors should use this window to submit comments and review their structures. Symbolic politics has a price. It would be paid not by the housing market, but by the financial centre.

Dr. iur. Alexander Schiemenz, LINDEMANNLAW , FuW opinion piece, June 2026

On 14 June, Zurich rejected three popular initiatives on the housing shortage: the left-wing housing initiative, the left-wing tenant-protection initiative, and the centre-right home-ownership initiative. All defeated. And yet the electorate said Yes twice: to the counter-proposals of the Cantonal Council. This is not a contradiction. It is a precise political statement. Voters do not want ideology. They want solutions.

The situation is well known, but it deserves figures. The vacancy rate in the canton stands at 0.48% in the city itself below 0.1%. Of around 224,000 urban apartments, just over 130 stand empty. Asking rents have most recently risen by 8.5%. Anyone looking for an apartment in Zurich today knows: this is not a market correction. It is structural scarcity.

“A No to all three initiatives is not indifference. It is a rejection of politics that prefers posturing to building.”

1. What does the counter-proposal to the housing initiative provide for?

The counter-proposal to the housing initiative receives 57.9% Its core: simpler zoning and building-law requirements, faster permit and appeal procedures, and the option of taller buildings. The Cantonal Council must present implementing legislation within three years. This is the opposite of the rejected initiative, which sought to create a state housing authority with 500 million francs in start-up capital.

2. Where are the legal limits to faster construction?

Legally, this is demanding. Zoning lies primarily with the cantons and municipalities, but federal law sets limits: the Spatial Planning Act, the RPG, prescribes how densely, how high, and how quickly construction may take place. A cantonal counter-proposal that shifts these limits may founder on federal-law barriers. The decisive question is whether the Cantonal Council genuinely opens up new room for manoeuvre or merely reformulates existing instruments. Will taller buildings in residential zones actually become eligible for permits, or will objections continue to block every second project? This is where the real test lies.

3. What does the counter-proposal to the tenant-protection initiative deliver?

The counter-proposal to the tenant-protection initiative comes to 54.3%. Its content is more targeted than the initiative it replaces. From 20 simultaneous tenancy terminations onwards, a landlord must submit a termination plan, inform tenants at least one year in advance, and examine whether construction measures are also possible while the property remains occupied.

4. Why is this tenant-protection counter-proposal legally delicate?

That sounds moderate. Legally, it is delicate. Tenancy law in Switzerland is federal law. The Code of Obligations governs termination, rent, and tenant protection conclusively at the federal level. A cantonal counter-proposal that regulates landlord conduct in termination situations moves at the edge of what is permissible under federal law. As soon as a cantonal provision intrudes into this core area of the Code of Obligations, a conflict of precedence with Art. 49 of the Federal Constitution looms. The first serious application of the counter-proposal will end up in court. With what result remains open.

5. What does the result now mean for the Cantonal Council?

Having adopted two counter-proposals is no free pass for the Cantonal Council. It is a mandate with a deadline. Those who supported the counter-proposals in order to prevent the initiatives must now deliver. This applies to the centre-right parties, which lobbied for years against tenant-protection rules, just as it does to the left-wing parties, which will now press to exploit the counter-proposal to the tenant-protection initiative to the maximum.

The political compromise has been found. The legal dispute over interpretation is only beginning. Every implementing provision will be challenged, by one side or the other. That is precisely the price of a ballot result that delivers no clear majority for one model, but a narrow majority for two different models at once.

Zurich needs more apartments. Zurich also needs tenant protection that works without deterring investment. These two goals are not mutually exclusive. But they cannot be produced by popular votes. Popular votes set a direction. The work that follows is craftsmanship: laws, ordinances, procedures, courts. The 14th of June can be a turning point. Greater Zurich is growing, the infrastructure is not keeping pace. That can be changed, if the legislature seizes the opportunity and finally introduces the processes that enable fast, reliable construction. The conditions are there. The excuse that it cannot be done, no longer is either.

Five questions Switzerland must answer

1. Is the supply gap real? Switzerland consumes 57 TWh today. By 2050, demand rises to 75–90 TWh. Beznau, Gösgen and Leibstadt go offline. That is a structural gap of 20–35 TWh. No scenario closes it without either new baseload or permanent import dependency.

2. Was the construction ban ever a direct democratic mandate? The 2017 referendum approved the Energy Strategy 2050 as a package — not a standalone technology ban. In 2003, two thirds of Swiss voters rejected both "Power without Nuclear" and the MoratoriumPlus. In 2016, a majority rejected capping plant lifetimes. 59% of Swiss people today consider new-generation nuclear sensible.

3. Is this energy policy — or infrastructure policy? Three million EVs, AI data centres, heat-pump districts. Electricity is the foundation of Switzerland's next economy, not one variable among many. The decision being made now determines what infrastructure exists in 2045. That is not an energy question. It is a sovereign infrastructure decision.

4. What does import dependency actually mean? Every TWh Switzerland imports is a TWh produced elsewhere — in French nuclear plants, in German gas turbines, in coal-backed European grid capacity. Energy sovereignty is not an abstraction. It is a geopolitical and economic asset that Switzerland has historically protected and is now at risk of quietly surrendering.

5. Are new reactors compatible with modern urban planning? Small Modular Reactors (SMRs) have a footprint of half a football field. They can supply both electricity and heat for an entire urban district simultaneously. The question is no longer whether nuclear fits a sustainable city. It is whether Switzerland can afford not to evaluate the option.

Five things that need to happen now

1. Lift the construction ban — and open the technology assessment. Not a decision to build, but a decision to evaluate.
2. Commission an independent feasibility study on SMR deployment in Switzerland, separate from lobby positions on both sides.
3. Define the grid investment required to close the supply gap regardless of the nuclear outcome — the gap is real irrespective of what fills it.
4. Set a clear timeline: if a referendum is triggered, it must be conducted on the facts of 2026, not the fears of 2011.
5. Separate the sovereignty question from the environmental debate. Both deserve honest answers. Conflating them serves neither.
