You guys are really pushing the line hard, huh?
Only "fault" from Tesla is not being more clear about what the autopilot is for.
Also what I would do, at least until they make it better, is to raise the threshold of uncertainty after which the autopilot stops working and human driver is required. Just stop the car and force the driver to take the wheel.
I guess "partial driving assistant" doesn't sound as good, but might be a better term.
