Wow... that would drive me insane... but then my major pet peeve are people and the way they forget how to drive... you know, no blinker when turning, pulling out in front of me from what should be a stop sign and I have to slam on the breaks, those who don't know that merging on the highway - it's not all about them going 35 into 65 MPH traffic, in a turn lane trailing the car a head of them when the light is clearly red... and now I'll had honking at the wrong time to that list...
*Wheff* I've had that bottled up for a while...

This is why my hubby drives most of the time... I have problems with stupid people and the cars they drive...
