As of February 24, 2026, Britain stands at a policy crossroads. The government is consulting on whether to dilute its zero-emission vehicle (ZEV) mandate—the regulation that prods automakers into selling ever more electric cars. Few companies have more riding on that decision than Polestar, whose largest national market is now Britain. My view is intentionally blunt: the mandate is working, it should stay intact, and reopening it again in a couple of years would be a mistake.
Those of us who sell only electric cars can be dismissed as biased. But the issue is not one company’s product lineup. It is about whether Britain—and by extension the United States—decides to win the next automotive race or cede it to markets that are already running faster.
The familiar criticism of EV mandates runs like this: regulators are overstepping the consumer, and political targets are outpacing demand. If that were true, Britain would be in trouble. The registration data suggests exactly the opposite. Battery-electric vehicles took more than a quarter of new cars in the latest month, an increase of more than a third from the year before. Buyers are getting younger, with the median EV customer now around a decade below the industry average. For a growing share of under-50 households, combustion is not part of the initial thought process.
These numbers are not an argument for pulling back. They are an argument for keeping the foot on the pedal. Even after counting the mandate’s built-in flexibilities, manufacturers were expected to reach an effective 24.6% electric share this year. The market has already delivered 26.2%. That gap is the single best indicator that the policy is not forcing a reluctant market forward. The market is ahead of the rule.
Britain is not an outlier. France has seen EVs take well over 40% of new registrations in a single month, and Germany has produced months where electric cars outsold petrol and diesel combined. Since roughly three-quarters of cars built in the UK are exported, British plants depend on staying attractive to European customers. If the domestic mandate is weakened, those plants do not gain a domestic breathing space; they lose a long-term investment case.
Why should an American reader care about a British regulatory consultation? Because the U.S. is living the opposite version of the same story. Federal EV policy is a series of reversals. The tax credit has been expanded, capped, narrowly included, and politically challenged. Emissions rules have gone from stringent to relaxed to litigated, with different states claiming different calendar dates. An automaker planning a U.S. EV launch has to check both federal law and a patchwork of state programs. That does not produce an open racecourse; it produces a waiting room.
California’s Advanced Clean Cars II rule is the strongest U.S. analogue to the ZEV mandate, and it is doing what a durable target is supposed to do: pulling investment into charging infrastructure, battery manufacturing, and platform development in states that follow it. But a single state’s standard cannot replace a coherent national signal—and the fight over state versus federal authority makes planning even harder. The British experience offers a different lesson: a national mandate, if politically protected, can be a gift to the supply chain. It gives every company the same fixed point on the map.
The missing ingredient in America is not demand. It is predictability. Investors do not price leniency; they price future assumptions. A decision about an EV platform taken today reaches a customer five years from now. During that interval, companies need to contract battery capacity, retool platforms, retrain assembly and service workers, and build software-like capabilities that didn’t exist in most automakers a decade ago. Every time the target is reopened, those choices get harder, slower, and more expensive.
The British mandate is under attack from two directions: those who say the requirements are too strict and those who say they are too rigid. The first group points to a steep ramp between now and the end of the decade. There is room for a grown-up conversation about the shape of that curve. But that is very different from reopening the destination. The second group frames flexibility as a virtue. Flexibility, however, is the enemy of investment when it becomes discretionary.
Policy certainty is industrial policy. With it, the private sector builds things. Without it, it waits. There is an already visible example in Britain: our Polestar 5 performance flagship is being engineered in the Midlands by one of the world’s strongest motorsport talent pools. That project is a direct result of international manufacturers believing that Britain’s electric future is real. Dilute the mandate, postpone the target, and future engineering contracts will start to look elsewhere.
The downstream effects are broader than car factories. EV-specific supply chains need to be built. The servicing and repair network for high-voltage systems needs training. Charging installers, grid software, battery recycling, and local software development all follow the original commitment. Consumers see the outcome as more model choice, keener pricing, and fewer software glitches because the companies doing the engineering actually believe the market will be there.
Trade policy is adding another layer of uncertainty. The U.S. has embraced tariffs as a central tool for reshaping the auto industry, while Europe promotes “Made in Europe” rules. Britain needs closer alignment with European value chains, but it should not become a closed shop. The same warning applies in the U.S.: a defensive industrial policy that treats global capital as unwelcome will not serve a transition that depends on the world’s best technologies being developed locally, not just assembled locally.
Strong countries do not try to develop every component inside their borders. They win by attracting capital, talent, and technology from everywhere. That is how Britain built motorsport expertise, how America built Silicon Valley, and how global EV firms choose where to launch their best products. The signal a market sends through its rules is more important than any single tariff line.
The politics of the internal-combustion engine is a rear-view mirror fight. The generation buying its first car in 2026 does not agonize over petrol versus electric; it chooses among electric models and asks which one fits its budget and habits. That is not a coastal fad. It is a demographic turnover.
Britain’s consultation will close, decisions will be made, and the market will keep moving. If British policymakers choose to protect the past, they will learn what every automaker already knows: the future will not wait for the rules to catch up. For America, the same choice is being made state by state, agency by agency. The smartest move is to learn from Britain’s success and its current moment of self-doubt. The worst move is to repeat the mistake from scratch.
