I havent tried tesla autopilot yet so I don’t know how much easier it makes driving, but if steering[1] keeps you from doing these things ... should you be on the road at all? If you’re too tired to both steer and maintain situational awareness you should probably take a rest :/
[1] steering, more like keeping the wheel steady on the freeway. Afaik Tesla can’t autopilot on the twisties yet anyway
