…at least for me. No, get your mind out of the toilet–that’s not what I’m talking about. I’m talking about the top ten irritating things that other drivers do. And hogging the left lane is much more irritating to me than someone on a cell phone. My attitude toward cell phone use is like my attitude toward drug use–if it impairs your driving, then don’t do it, but I don’t care about it intrinsically.

The Freepers have comments, and I agree with this one (slightly edited):

No.2 is the worst.

In fact. No.2 causes every single one of the other annoyances.

All of them.

The slow “safe” drivers are the most unsafe drivers around.

They are indecisive, scared, do not follow the flow, have no clue about the passing lane, and do not use their blinkers.

They cause people rage, especially because they will not get ticketed, even though they are causing the biggest problems.

Someone speeding 10 mph over the speed limit with the flow and control of a car is not a safety hazard at all.

Slow idiots with no clue are.
