In fairness, the original topic was things that are legal but much more dangerous than Autopilot. Texting while driving - or even holding a cell phone while driving - is certainly not legal anywhere near me these days.
(But yes, a lot of folks do it, and yes, it is very dangerous.)
Posts on several threads on TMC seem to argue that AP is dangerous and should be outlawed because people can do stupid things against the advice of Tesla. I don't see that that is any different than making a car stable enough that people can generally text and drive and get away with it till... well, till they can't. If these people were consistent in their logic they would be pushing for cars to have built in instabilities so that you had to keep both hands on the steering wheel just to stay in the lane. That would prevent texting while driving along with holding a cell phone.
