Why is California (and perhaps the political left in general) obsessed with banning or requiring things? Bit by bit the choice individuals could make privately or locally is being taken away from them. In a very real way, freedom is being replaced with decision-making by the state at broader and broader levels of jurisdiction. This is not a good way to manage society.
If the value in adopting electric vehicles is there, let people recognize that value on their own and decide on their own to adopt it. Alter incentive structures in minor ways but don't override an open-ended libertarian choice architecture with top-down authoritarian decision-making.

In 1952, due to a combination of weird weather and coal emissions, a smog in London lasting four days killed at least 4,000 people over its duration and possibly as many as 12,000 people over the next few months.
This lead to the phasing out of domestic coal in cities, regulation on power plant flue gas, and so forth, over the following decade. People, and the energy industry, kicked and screamed, but the government (at the time controlled by noted lefties the Conservative party) did it anyway. There were two more incidents in 1957 and 1962 killing 750-1000 people each, but that was about the end of it.
Maybe in a parallel universe the libertarian government of the UK did nothing, and people reduced their emissions on the same timeline anyway. But I think it's somewhat more likely that in that parallel universe people are still dying horribly in their thousands every time the dangerous weather conditions (cold, no wind) repeat. People are notoriously bad at externalities.
