Could a self driving “all bed” car be built on the model 3 platform? This would be a flat deck just above the top of wheels from the front to the back (6ft x 15ft) with pop up side rails. No seats, no steering wheel, no AC, just a interface pad on the side. It could follow behind you like a trailer (but not physically attached) or be sent off on it’s own. This should cost less than a model 3 to build and would have more utility than a typical truck since none of the space is wasted for humans and the bed would be huge. It could also be used to make a really nice pop up travel trailer. If this existed would you still prefer a truck?
