Most other attempts at redesigning the truck bed have failed. The Chevy Avalanche and Cadillac Escalade EXT never sold well and were eventually cancelled. The Honda Ridgeline sold poorly and eventually was redesigned with a regular truck bed with straight walls. The problem with trucks with high bed walls is you can't throw gear, tools or materials over the side of the bed. You can't climb over the side of the bed to tie things down, and you can't (easily) put a custom cap or camper on it either. It's hard to see the Cybertruck selling real well once the initial rush wears off.
