OK, here's my gripe. By the way, it seems everyone who has posted so far is British. Mine is an American problem. Does this happen in Britain, too?

Once upon a time people used to obey speed limits. Then, during the 1973 oil crisis the US government imposed a national speed limit of 55 mph. Before that, speed limits were a state and local concern.

The new limit was obeyed at first, then speeds gradually crept up. It got so that, if the posted limit is 55, people think they have a right to go 65. If the limit is 65, they think they can go 75. And they get away with it. The police wouldn't DARE to try to enforce the limits as they are posted.

In fact, a lot of people treat the limit as if it were a lower limit. If you obey the limit, people will honk at you, tailgate you, zoom past you at the first opportunity, and blame YOU for creating a traffic hazard.

This really pisses me off, but I don't know what to do about it.
