In my mind there's a big difference between, say, driving "traffic" speed (where traffic is moving 10-15 mph faster than the speed limit), and drunk driving or failing to stop at a red light.  The former actually improves safety - most accidents are caused by speed <i>differences</i> between vehicles, not absolute speed.  The latter is a good way to kill someone or get killed.<p>And in my experience most traffic enforcement seems to be against the latter kind of behavior.  (Well, except the cops who sit at the bottom of a hill where the speed limit drops from 35 to 25, because their town needs revenue.)  I've never known someone to get pulled over for speeding when they're driving traffic speed on a highway, even if there's a cop right behind them.  I think people should and do get pulled over if they're weaving or blindly zooming through red lights.<p>Isn't it interesting that something as clear cut as <i>traffic laws</i> could spawn such a debate?  Pretty good evidence, IMHO, that laws are not clear-cut and there's room for judgment calls in a lot of them.
