The EV market is in a slump right now in the US, as well as China. Not in Europe though. Will be interesting to see what happens next year if we have a Republican in office. If it is a Democrat, EV's will get a new boost in sales. Republican, EV's may be in trouble for a few years. On the other hand, if the Republicans don't support EV's China will capture the entire world market for years to come. So who knows?
Tesla has a huge advantage above anyone else, due to its vertical integration. They are now even looking at lithium refining. The competition will bleed big time until they eventually catch up, if ever.
On the whole climate thing, humans do what they have to do. I don't think major progress will be made in our lifetimes, or until such time as humans are forced by nature to make drastic changes. If Iran gets their way and gets Nukes, the whole world landscape may change, as they don't care about anything living.
If Solid State batteries find their way into EV's (Seems like everyone is working on that) the whole dynamic will change. After that buying an ICE will be like buying a Harley Davidson. A cult favorite, years behind in technology.
