The GM Ultium concept is interesting, not a breakthrough of course, but interesting. I'd say we're one major battery advance short now. Or, a major government tax credit short. Take your pick. GM and Ford and VW "think" the market is going EV in 14 years in a Big Way. We'll see, maybe.
I'd take Cadillac to EVs, perhaps, in cars, and let Chevy remain mostly ICE. Buick is stupid to me, they shoulda kept Pontiac.
