I don't drive a GM or a Tesla or any electric car and I have no skin in the game, but it seems to me that GM's differentiating feature is that you can walk into a dealership and buy one right now, today, and drive it away the same day. I see far more Volts/Bolts than I do Teslas. The difference between the Bolt and the Model 3 is that you can buy the Bolt right now.

If anything it seems to be Ford and Chrysler doing the bare minimum. They offer EV versions of their cars, but they're not common and not pushed very heavily. At least GM has an all-electric model that stands on its own and isn't just an EV variant of another model (it's not "the Chevy Bolt EV", it's just "the Chevy Bolt" because there is no "Chevy Bolt ICE".) GM's electric offering was built from the ground up to be an electric car, and has won tons of awards for actually being a good car.
