At this point I think I'll get my Hummer EV3x before receiving the Rivian. Such a disappointment. I wouldn't doubt they are heading to bankruptcy if they can't get out in front of all the other EV's that are coming.
I received the exact same delivery window for the r1s. I'm thinking if my Hummer reservation happens before this then I'm bailing on Rivian. They have let me down too much.
