The back tailgate is just an enormous grey not-quite-flat slab that looks exactly like a commercial kitchen dishwasher door that someone clicked on in a CAD program and stretched to truck size.
And the stainless steel panels overall, despite being nearly brand new already looked like they had a bunch of fingerprint streaks or some sort of surface discoloration in a number of places, that really detracted from what was, I expect, an intended effect of clean severity. All the proportions read as very ungainly with the weight gathered in awkward visual masses, at least when seen up close from eye level. The panels already displayed just the slightest bit of imperfect matching between adjacent coplanar surfaces. I can't imagine how rough the thing is going to look in two or three years.
I would take a rivian over two of these things any day of the week, even if it does look like Bomberman.
Has a longer bed than the F-150.
The thing that I can't get over is the raised walls on the sides of the bed. The appeal of a pickup is that you can easily get things in/out of the bed without having to go through the rear of the vehicle; the raised walls are going to make it so much harder to quickly huck a heavy toolbox into the bed.
Elements like the sloped bed walls and elevated external sides of the bed make it clear that this vehicle wasn't designed to be used as a truck.
