I wouldn't say "most". I've tested Toyota and Nissan, and they can't even drive on a normal road and are barely useful on a motorway. Every time there is a merge lane on the right they will both creep into that lane once the lane markings disappear. Nissan's ProPilot can't handle a regular meandering road, at the first sign of a tight corner it will give up, but not before pretending that everything is fine leaving you with 2 seconds to stop it from driving off the road. I think that Tesla is about 20 years ahead of Toyota and 50 years ahead of Nissan.
