I was thinking about that and it would have to be perfect if it traced the actual road. Imagine if it traced slightly off the road or into another lane, the first person who would follow it into oncoming traffic would put an end to the whole project.

Maybe recognize and highlight exit signs that you need to turn off on. It's usually high on the windshield and therefore not as distracting.

Parking assist is another thing that isn't quite right. It alarms me when I'm still a foot or two away. When I turn it off, I park much more precisely. It probably made a hell of a lot of money though, selling to car manufacturers.
