There is nothing more aggravating to me than bad drivers... Not just those "Sunday drivers" or "LA drivers" (yes they are bad drivers too) but those that really do not pay attention to anything around them. Those that drive like they are the only ones on the road... are the only ones on the road that MATTER. Ugh.

Some of the worst:

I hate when I am trying to merge onto a freeway in an exit only lane and the guy behind me (or the guy behind him) decides he is in too much of a hurry to wait his turn and moves into the lane I am trying to merge into only to match my speed right next to me so that I cannot move over, ignoring the blinker I have had on for the past 2 minutes.

Or.

When the guy in the turn only lane previously mentioned is trying to get into my lane by speeding up to squeeze in the little space that exists between me and the semi in front of me, causing me to have to hit the brakes, instead of staying at his current speed or slowing down a bit to go behind me (where it's entirely empty).

Or.

When the guy next to me decides to change lanes all of a sudden because he fancies being in my lane in front of me but is doing 15 miles an hour less.

Or.

The lady sitting in the right hand turn lane who will not, for the life of her, make a right hand turn until the green light says she can go... even though there is NO OTHER TRAFFIC blocking her way (and no signs forbidding it).

Or.

Those bastards who, upon arriving at someone's house to pick them up, honks their horn repeatedly instead of either getting out and knocking on the door or using their cell phone to alert their friend of their arrival.

Yep.

Or.
