I agree, I would keep it is strictly a "backseat driver" assistant, looking to intervene when you're stupid, but the way Tesla is marketing this feature is dangerous. The software should not let you take your hands off the wheel and offer no "off switch" to get access to hidden 'full autopilot' mode, because people's lives are gated by the riskiest, dumbest drivers. This is one issue where being "open" with respect to the system software is bad, and being more "Apple"-like in imposing restrictions is for the greater good.
