If tesla’s autopilot were available to all vehicles for use only on highways (which is where most Tesla owners only use autopilot), the number of highway deaths due to inattentive drivers causing rear-ending accidents would drop to near zero overnight. It is so vastly superior to distracted humans on a highway, it is a “seatbelt” type revolution in terms of human safety.
But Tesla doesn’t seem to push this specific use-case resticted angle of it, Musk is focus on full self driving.
