I'm sorry, but everything that you said in relation to Tesla there is wrong. My Nissan with ProPilot can also control the throttle, brake, and steering, but that doesn't make me a mere passenger any more than cruise control does.

It routinely false positives on frontal collisions and occasionally does things that would be dangerous if I weren't driving.

The driver in a Tesla is not a mere passenger, regardless of whether or not they have enabled autopilot. The initial warnings on enabling autopilot as well as the attention nags on the steering wheel all make this perfectly clear to the driver.
