As long as the lanes are clearly marked or there's a car in front of you AND there's no forks in the road AND you keep your hands on the wheel AND there's no construction zones with wonky lanes AND the curve on the road isn't too much AND there's no large crests and turns at the same time AND etc. etc. etc.Really? Did you buy a Tesla or something else? Because my Tesla, does exactly that. Once I get on the highway, I switch on AP, and it drives all the way till I get to my exit. Check the badge on the rear to see if you have a 'T'. I honestly don't understand what you mean it is not doing "on ramp to off ramp"
If you were new to Tesla and listened to the promised hype from Elon, he was selling a car with L2 capabilities like an L3 car. Hindsight is always 20/20.
Look, I agree with you, AP1 is pretty damn awesome. I've logged tens of thousands of miles on it. BUT @Electricfan has a point. Tesla oversold the capabilities of the car.
