Can't you go theoretically go to the toilet on autopilot? It won't land for you, but while turned on it will keep the plane aloft until fuel runs out, no?
Tesla was selling something which is marketed as being able to handle freeway driving under good weather conditions. It can't be trusted to do even that right. The "rams into vehicle stopped at left of roadway" feature is unacceptable. That's an expected possibility on a freeway. Users would legitimately expect auto-braking to activate for that.
