If I take a drive on a highway in the Tesla and the signs says 80 the car won't just decide to suddenly go 125 just because it feels like having some fun. You speed, your car doesn't, unless it is faulty.

Tesla's aren't self driving no matter how many times Elon says so. It's not even the best in most tests in being a driver assistance..

Being a fan of a car and not being able to see it's faults isn't healthy.
