Here in the Memphis area, we have the additional problem, on the interstate loop, especially the south 240 loop, of two or three cars or rockets racing each other. They dodge from lane to lane at 70 mph and up, tailgating, near misses on passing and cutting off other drivers. Down right dangerous, even if you're in a cage, and even more so, on a bike. Law enforcement looks the other way. Best defense is stay off the loop or ride in far right lane, even thought they aren't opposed to passing on the shoulder in order to win their race. Karl can verify this, I.m sure.
