So basically GM is done, because talk to anyone in the Midwest and they’re not going to buy an EV Truck.
There's a lot of "rolling coal" sorts, sure, in places like the Midwest, but even many of them come away from test drives of EV trucks impressed. EV trucks nearly market themselves because torque is always the main problem/focus/interest of anyone that uses a truck as a truck (for hauling), and diesels can't beat electric in practice on torque.
