Here's the other side of the coin (no flames, please!). I drive close to 80mi/day to and from work. I would prefer to spend as little time on the road as possible (ha -- try that driving the 101 and 405! ;-) ), so yes, I prefer to go a fast as reasonably possible, when I can, but I don't tailgate. BUT, I do resent people who drive the speed limit or below in the number 1 lane when there's 6 or more car lengths between them and the traffic ahead, which is clearly moving faster than they are. The CA driving codes state clearly that if you're not drive the speed of prevailing traffic, you should move over (when safe) and let faster moving vehicles go by.
So, if you're one of those slower moving drivers, please be considerate! Passing should be carried out on the left, not the right. The fastest two lanes of traffic on the freeway should be the number 1 and 2 lanes. You should never make a faster moving car pull to the right to pass you! If you want to drive more slowly, please drive in the number 3, 4, or 5 lanes.
The same goes for the diamond lane, although I can certainly understand if carpooling drivers moving at a decent clip in the DL don't want to have to pull into regular traffic that may be crawling. Still, there's nothing more maddening than sitting behind someone in the DL who's going less than 65mph with a clear stretch ahead of them! I will say that some of the problem I think is caused by the way DLs are handled in L.A. In N. CA, you can legally merge in and out of the DL at any time. Traffic definitely flows better with this set up, because if someone needs to leave the DL, they don't have to slow everyone else down while trying to merge into regular traffic in a very short interchange space to exit the freeway. Also, if you're driving behind a pokey little puppy who refuses to give way, you could pass on the right at any point.
Oh, and my other peeve is drivers who are totally oblivious to what's going on around them because they're talking on the cell phone. They should get a hand's free device for heaven's sake, and check their rear-view mirror once in a while. Everyone will be safer and happy for doing so!
