Re: No wheel is one thing
It might look like when Airbus ditched the traditional yoke for the sidestick. I think Tesla might seize this moment.
Ford, Mercedes, Saab and Honda have all experimented with joystick-controlled cars. All gave up: you simply cannot achieve the precision required, or the haptic feedback needed, with a stick. Although yokes were traditional on modern airliners, sticks work fine on light aircraft - and remember that an Airbus is flying itself for perhaps 95% of the time.
