While I am here, I should tap out a little rant about cars. I have a theory - many car drivers behave badly/dangerously because drivers are so thoroughly enveloped in their sound-proof machines, there is no opportunity for the rest of us to give them a good clip around the ears when the do something really dangerous - like get agro at someone. You can't even give them a proper piece of your mind when they are hiding away in their little steel coffins pretending not to notice you flip them off. So they do it again next time, do something stupid again like tailgating, they get away with it, it makes them feel tough, and the cycle continues till they kill someone. Damn fools.
Is there a national database of bad drivers? It should be advertised on TV, if there is. Seems like we could develop an "X strikes and you are out" kind of policy.
