Look under any RWD IRS passenger vehicle and you’ll find nearly every single example uses CV axles, not u-joints. U-joints have famously irregular speed variation as the angles change in steady rotation, so the constant velocity joint is far more common for the half axles
Comment on Tesla confirms it has given up on its Cybertruck range extender to achieve promised range

As for rear, they don’t need CV axles. Two simple cross couplings are enough. The speed variability happens significantly when the wheels turn, going up and down is a negligible issue. Cars have been using the much chapter and simple cross couplings in the rear for decades.

The CT has four-wheel steering, so yeah, it’s actually more complicated than a regular truck in that regard. I remember reading something about the mechanisms to make that possible taking up a shitload of room.

Oh yeah, forgot about that. They had to bolt that on to have any chance of having a reasonable turn radius.
