i'd love simplifying cars on two fronts: (1) the use of standard knobs and buttons for radio and air conditioning on the dash (in addition to a touchscreen for maps), and (2) removal of takeover features like lane assist and collision avoidance. i don't believe these "safety features" actually promote safety. instead, they allow people to be even more distracted and low skilled.
in one of the cars i rented recently, the collision detection system activated, not once but twice, while i was trying to avoid a collision. the autmatic braking almost caused an accident by disregarding my direct control. afterwards, i looked for a way to disable automatic collision avoidance but couldn't find it.
