I mean, given some localities starting to have laws to the effect that cars sold have to be electric after a certain date, and some manufacturers stopping development on new ICE engines with the intent of moving entirely to EVs eventually, they're not going to have a choice some day, if they want to keep selling cars.
I work in the automotive industry, and my company supplies the software to dealerships. It cannot be understated how important Service is to car dealerships.
For all the cost that goes into sales, the most successful dealerships make 60–80% of their profit via service. Car sales have a relatively thin profit margin. I don't know what the solution is to that relationship, either.
Maybe Carvana-style virtual dealerships are the only viable path forward for EVs.
I believe the OP's point is that because EVs still use fossil fuels and companies still make a massive profit from it, it's a scam but I could be wrong.
