Careful about painting all automobile drivers with too broad a brush. They're individuals, just like we are, and just like we have ardent FRAPers and ardent VC'ers, there is a variety of attitudes among motorists, as well. Some are inconsiderate, rude, condescending jerks. Others are considerate, polite, and retained their kindergarten sharing skills. A strong majority of motorists view cyclists as inconsiderate, rude, and condescending (and in some cases, they're right, because many cyclists fit that description quite nicely). Could it be that we're all just human, and a certain percentage of any group we join is going to be inconsiderate, rude, and condescending?

I take my lane, and I'll scoot out of the way of a right-turning motorist at a stoplight if I can. I've had encounters with jerks, and someone once tried to run me off the road. Out of the thousands of cars I've interacted with, this was an extremely unusual case. Additionally, I've had 10 drivers stop and ask if I needed anything while I was sitting on the side of the road taking a break from one of my longer rides.

We're all just people. The rest is jingoism.

[edited to add: Looks like Genec and I are on the same page with this, except that I get off the bike because I'm lazy]
