So? Governments have jumped on the bandwagon with subsidies and threats of regulation. They have to produce something and they will. The question is whether the end result is something consumers are going to have to be forced to buy or if it will be something that is actually better than ICE engines.
If there was any sanity in government the focus now would be on plug in hybrids. This is tech that exists and works for real world applications. It would also allow the gradual investment in the charging infrastructure needed to support wide spread use of EVs. Unfortunately, too many people are star struck by Elon Musk and his fancy toys.
Emission and safety standards were all mandated and there were exactly the same arguments and rationalizations at the time. Every vehicle we drive today is far better because of them. This time, the manufacturers are jumping on the band wagon, not bitching about it and pushing back.
That said, I don't know that Tesla will be an eventual winner here, the likes of GM, VW, Ford, Toyota etc have deeper pockets and a huge manufacturing infrastructure that can be retooled instead of being built from scratch.
