Here's another kind of driver I can't stand. The ones who don't understand the concept of dual turn lanes.

I'm approaching an intersection on a 6 lane road (3 lanes in both directions) - the right lane can either go straight or turn right; the center lane can go straight or turn left; and the left lane must turn left. The driver ahead of me can't decide in which lane she wants to be. (No, I'm not making a comment about women drivers when I say "she." It really was a woman driving.) She's in the center lane, starts to move to the right lane, but decides she wants to turn left so she swerves into the left lane. Since this all took place about 10-15 feet from the intersection, she is now sitting in both the left lane and the center lane. All she needed to do is stay in the center lane!

There's also an intersection near where I work that, I have to admit, is a little confusing. When south-bound Amon Carter Blvd intersects Trinity Blvd, it widens from 3 lanes, into 4. Since it ends at Trinity Blvd, the 2 left lanes are left turn only, and the 2 right lanes are right turn only. At least once or twice a month, someone in the center lane - which becomes one of the right turn only lanes - doesn't pay attention and turns left from that lane.

The other drivers who drive me crazy (pun intended) are the ones who get into the left-hand left-turn lane and, when they make the turn, swing out into the right-hand lane of the street they're turning onto.
