In the last week or two there have been two incidents on national news where two Tesla drivers were filmed apparently sleeping while driving. Terrible idea whether they chose to or they drifted off. But the part few, if any, are talking about is those who fall asleep in ICE cars. I have caught myself drifting off and I had to stop and wake up with No-Doz, now I guess energy bars might work. The BIG difference in ICE cars is that they often just drift of the road and the injury or death cannot be exactly tied to sleeping while driving. That big droning ICE engine and cruising on the highway are not conducive to alert driving. If you have a car with lane keeping and you are in cruise mode you could go miles before an accident just like in a Tesla. With a Tesla the company can confirm whether or not the driving was in AP when an accident happened. Not so much with most cars on the highway.
