There is a weight sensor in the driver's seat and a torque sensor in the steering wheel. If you leave the seat, autopilot will disengage immediately. If you take your hands off the wheel it will disengage in a minute or so. They also say it was traveling at a "high rate of speed", but autopilot will not go more than 5mph over the limit on surface roads. Something doesn't add up here.
They're pretty secure, though it wouldn't be impossible, I guess. They establish a VPN back to the "mother ship" and will only accept remote commands over that. If someone gained the owner's credentials they could send commands via the API endpoint used by the mobile app, but the capabilities there are pretty limited.
That said, adding the possibility of unauthorized access still doesn't make the story add up.
I tied Can and infotainment networks together in my Tesla for easier remote admin. It's pretty easy with hardware access
