If someone tailgates me, it only makes me want to drive even slower...and to match speeds with the slow driver in the next lane. I think I made a tailgater's head explode once doing that.

I also hate people who interrupt me. When I used to work in an inbound telemarketing company (people called me to buy the crap that's sold on tv) they would constantly interrupt me...usually when I was trying to answer their questions. I'd be giving them an answer to their question, and they'd start to yell at me about why I wasnt answering their questions fast enough...Because they were screaming at me, and I wasnt allowed to interrupt THEM! I had to wait for them to shut the heck up.

Another pet peeve is children wearing those Wheelie shoes. I've been run into so many times in WalMart and other stores that I pretty much have given up being civil to the parents of these kids. The kids skate into me, and I get kvetched at for being in the way? I'm not the one rolling down the aisles with wheels in my shoes.
