traffic

It seems like every day I come across a different trafffic/driving issue that annoys me. I think I could almost do a daily issue.

So for today, it's people that drive under the speed limit on the express way. how annoying is that? as well as how dangerous is that? expressways work because there is a reasonable expectation that everyone will maintain the same speed. well, at least within the same speed range. So how scary is it when you come up on someone going 10-20 m.p.h. under? didn't expect that. i certainly hope my brakes are good. so annoying.
