Conflicts do happen and you move on. There are a few times I'd love to put someone in their place but in reality it's just not worth it.
All these urban freeways in the Detroit area with a 55 mph speed limit, good luck getting anyone to go 55 the normal speed is probably 70 at the lowest and 80-85 at the highest. The Chrysler, Fisher, Ford, Lodge and Southfield all have 55 mph limits on some stretches and no one obeys the speed limit. When there's a lot of traffic on the Southfield you can't even get going more than about 60.
