They behaved irresponsible, but Tesla could really use actual driver attention monitoring. It should not be possible to have no one sitting in the driving seat. They seem to have a broken attention monitoring system that is easily tricked.
Yeah I generally agree with this. Forget the camera stuff the other commenter mentioned, the seats have a weight sensor already for other stuff like making sure you don't get out of the car when it's not in park. I can't believe AP doesn't use that, unless the owner here bypassed that by shorting the circuit or something.
