I mean a lot of them can. But those design features are completely orthogonal. Nothing about "self driving" requires stupid and unsafe door handle design. Tesla has clearly fallen into the trap of thinking that making something futuristic requires changing even the things that work just fine and don't require futurifying instead of realizing that the best future improves the things that could work better while leaving other things alone.

Many of these cars can drive themselves better than Teslas can.

My Subaru may not be able to change lanes but it also won't run straight into a truck, police car, ambulance, tree, or wall like a Tesla will.
