> "We specifically advise against its use at high speeds on undivided roads," it said. Tesla states clearly in its owner's manual that drivers should stay alert and keep their hands on the wheel to avoid accidents when the Autopilot feature is engaged. Most people don't read the manual unless what they're doing actively doesn't work. Especially with press surrounding Autopilot saying it's basically the best self driving car and is completely trustworthy (even if they don't explicitly state that, it's still implied), it's not unthinkable that someone would completely trust the car and not worry about sensors. The car should be much more proactive at getting the user's attention, either by actively slowing the car down to some safe speed with cautions on and/or significantly lowering the time limit of taking their hand off the wheel before any indicators appear. I'm not sure about the former, but the latter is done in every other car that has this kind of technology (e.g. cars with Lane Assist) and the time is very low, around 10 seconds.
