New video of Tesla crash demonstrates the problem of semi-automated driving
I have a VW Golf and it has what it calls "adaptive cruise control". What makes it different from my older (simple) cruise control is that it will slow down and speed up again as necessary without my intervention. For example, if I set the speed to 70 mph and it gets close to a car ahead that is only going 65 mph, it will slow down and maintain what the software believes is a safe distance. Similarly, if a car in an adjacent lane changes lanes in front of me, it will slow down if necessary.<p>I do use it, but less than I did the old system: I just do not find it relaxing because I cannot really grasp intuitively when I need to override it. On standard cruise control, it was obvious to me when I needed to take over. Therefore I am more rather than less vigilant than I was with the old system.<p>I don't want to be too hard on the Golf: it has other safety features I really like, such as lane assist and automatic breaking. But I am not a fan of the adaptive control, and I think the article help me understand why: its a level 2 problem!
