I hear ya, the idea of PMM started when this happened:
Tesla Model S Makes Entry Into Bank By Crashing Through Brick Wall
At the time, it was only about a mile from my former house before I moved to Fremont to start at Tesla. This accident really got me thinking how things like this could be prevented.
If the AP system could remember that a parking maneuver had been completed, car was in a parking spot and the path ahead was NOT a drive-able surface, we could predict that the only, high confidence way out is reverse. So when the car was put into 'drive', NOT reverse like expected, then throttle applied, we could have high confidence that was PMM.
So great to see the Andrej videos where PMM has fully mitigated accidents; especially where loss of life would have been the most likely outcome.
