I'd be shocked if this wasn't available vehicles across the board. Though it is interesting that the Bolt is going to be the first vehicle to show it off.Not sure if it's been mentioned yet - the Hummer EV is expected to have GM's Super Cruise feature, but I haven't seen anything completely confirming it. (Super Cruise is similar to tesla's autopilot, not full self driving). I saw an article today that talks about the Bolt EUV being confirmed to have super cruise as an option....this basically means it should be available on the Hummer EV.
