If this stands the whole nation and most of the world will feel it. California represents such a huge market that the manufacturers are going to gear production based on what California mandates. It also will not be just California. Many other state governments are considering similar orders for the masses. The bad part is that "we the people" keep voting for those snake oil sellers.
To be clear, I don't have a problem with electric vehicles. I would buy one if it performed similar to my current vehicle and was priced the same. The reality is dealers don't even sell electrics where I live because they don't work well (I live in cold and snow country) and the price is too high. I've seen a Tesla or two driving around - in the SUMMER! I think they get parked in the winter. My town also has a couple of EV charging stations. I have yet to see a single vehicle plugged into one.
