Laws are laughable in the face of capital. The only reason we have electric cars in the first place is because persons and countries with capital massively invested in new technology.

Laws are the end of the political process, not the beginning.

Case in point, gas taxes just make people grumble and not necessarily switch to electric cars.

You know what doesn't make people grumble? Cheap solar panels / cheap cars that are the result of planned investment on a continent scale, funded by the government through both research and investment grants.

Money is power, and power is political. Passing laws without changing economic policies is how a country goes to irrelevance.

In the modern age one needs a long term investment plan. Without it, the entrenched powers (big oil, etc) exert their enormous influence to keep a country backwards. You need to fight capital power with capital power.
