Re: What a complete plonker!
So the Tesla system is even more screwed up. Even the adaptive cruise control in my Toyota slows me down when I'm still well back from approaching the car in front (detected by its radar) and slams on the brakes if I get too close before plonking my foot on the brake pedal (sensed by the windscreen camera). If I take my hands off the wheel for a few seconds, even that system warns me (and I found that out by trying to test the lane departure system on a deserted road).
Toyota makes no claims for autopilot - just driver aids. In fact, its literature and advertising downplay its ability.
