I'll go ahead and be the bad guy. I don't like my car that much. I don't like the number of people that have moved into my area in cookie cutter houses they can't afford, clogging up the roads around me. Therefore, I loathe spending any more time than I have to in my car going somewhere that used to take me half the time.
I'm 31 and I have toned it down a lot from when I was 17 or 18, but I will still go every bit of the speed limit and sometimes 5-7 mph more. I do not mind people who go the speed limit (or within 1 or 2 mph) I am perfectly happy to be behind someone like that. I have no respect for people going 7, 10, or 15 under in perfectly good conditions. The speed limits are established with an AMPLE safety margin, and if someone has a license, he should be able to do the speed limit or a close aproximation thereof. Otherwise they are wasting my time, plain and simple.
I do not tailgate others usually. That is tacky, and will probably cause them to go slower. Plus, if they stop suddenly for no reason, I am screwed as far as accident fault. (And you've gotta think, these people are going 25 in a 40 mph zone, they're liable to do any kind of wacky thing.) Sometimes I find myself closer than a 2 second following distance, just because of the sheer magnitude of the slowness of someone in front of me. I usually try to back off if I realize it, but in really bad cases, just idling keeps advancing on their molasses-like position, and it's difficult.
One other thing. I know for a fact that every driver out there found the accelerator at some point in their trip. Why is it so hard to find after being stopped at a light. Really, they don't have to wait for the car ahead of them to clear the intersection before finally inching forward!
