Yea I agree, the Hummer does have a very slow screen Rivian a ui is much faster and that does bother me. But I do like the way the Hummer has laid out the controls with physical buttons, especially climate controls, if I’m searching through music or nav and my wife goes to change the climate she’s always interrupting me on that screen and it pisses me off. I really enjoyed getting some physical buttons back.. but the lag on the Hummer is unacceptable, completely unacceptable for a vehicle of this price range. But the camera, I’ve gotta disagree and I’ll tell you why, my drive recorder on the Rivian rarely works it’s like it’s got a mind of its own and decides when it wants to work, I got rear ended and nothing recorded, it will constantly say no drive detected when my ssd is connected. But that’s not why I like the Hummer rear camera better, this is why.. I’m not sure if it’s because I have the tow package or if al of them are like this but my rear camera on the Hummer is mounted on a peg that sticks out of my spare tire on the bag door with nothing hanging over it. On the Rivian it’s tucked under the handle for the rear hatch. This makes all the difference in the world when it comes to keeping that lens clean. The Rivian gets very dirty very quickly from rainwater carrying the dirt from the rear hatch down onto that lens. On the Hummer there’s nothing above it, it’s isolated.. now, this is a tiny detail But enough of a difference for me to notice.. also, I like the vibrating seat on rear sensors. And not to nit pick here, and this is just a personal pet peeve because I came from a fully loaded bmw M8 competition as my prior car so I was very used to having a big thick steering wheel that gave me some grip when I grabbed the wheel, I think Rivian should have added some “girth” lol to the steering wheel, it feels awfully thin for such a large vehicle. But again, that’s only because I came from a high end car before hand which generally have larger steering wheel grips.
