I don't get it. Mandating that auto manufacturers sell a certain percentage of electric vehicles seems a bit like legislating the weather. If CA really wants to push people into electric vehicles, why not manipulate the demand for electric vehicles? Perhaps add another dollar or two to the gasoline tax?
Since conventional automakers don't seem to be willing to aggressively pursue EVs on their own, this seems like a reasonable approach.
Or, put another way, the consumers who continue to buy ICE cars, and in doing so create pollution, are helping to pay for the EVs that other people are buying.
