Personal vehicles are a very profitable market. The reason why we didn’t hear about them earlier is because they weren’t as profitable as fuel based ones. This means that if we are hearing about them now, then they have been extremely profitable. It has nothing to do with the environment. All those leftist politics are just ways to make big money. Just look at anything that has been promoted by politicians. Also, although I said “leftist” it does apply to all political parties/ideologies tbh.
