Pickup Trucks are work vehicles and are popular for that use. While the local punks might want to copy Daddy but be Woke at the same time might get an electric truck, the vast majority of PU's will continue to be the sort of thing that can be refueled from a jerry can in the field.

The cheap end of the Tesla's now cost what ICE cars do but everyone that buys them wants things like self-driving and dashboard navigation etc. which puts the price all the way back to the Tesla price of yesteryear. Are you going to pay a Ford F150 ICE for $37,000 or a Tesla for $127,000? That difference buys a LOT of gas unless you're social signaling like Krygowski.
>
> Chevy has canceled production of the Bolt because people want to social signal in a luxury car and not something that looks like it was made in China. The problem with Krygowski is that if his EV caught fire and burned his house down he would never admit it and would continue to tell us how great EV's are. Most people with EV's are this way. Where I ride are several pharmaceutical companies and the parking lots are wall to wall Tesla's. I imagine for most people that is a good idea since they live close and charging is minimal. But $90,000 price difference buys an awful lot of gas. Especially when the Federal subsidies on the price of electricity come off. Where do you suppose they are going to get the extra electricity when we are presently having blackouts all across the US. Even New York City had a major blackout in Harlem. (no wisecracks please)

Ford for example, "is set to lose $4.5 billion more this
year than expected on EV and battery production. "
