My car has adaptive cruise control. It automatically paces the car ahead with about a 2-second gap. It is absolutely wonderful for reducing stress and workload in heavy traffic. But the other cars... Someone will see the gap and race around me to fill it, as if I wasn't driving exactly the same speed as the car ahead. Causing my car to slow a bit to rebuild the gap. The next car back sees that and decides the first car passed because I'm an obstacle, and copies them. And so on. Until I'm driving 5mph slower than traffic, with a constant stream flowing around me.
