What gives you road rage the most often?

I won't get on the subject of people driving while on the phone, because we'll just end up being here all day. I think the single greatest annoyance are people who come to a four way stop and need to turn left, but don't use their turn signal. You both start into the intersection and they cut in front of you and flip you the boid and a look like you're a complete idiot for not "intuiting" that they wanted to turn left.

I think the thing that gets me the most is when people can see that their offramp is just ahead and wait until the last minute to drive accross 2 or 3 lanes of traffic to make the offramp. Other things that get me are when drivers wheaving in and out of traffic without lookingwhen changeing lanes. I ussually slow down for tailgaters because if they hit me, its their fault.

What really makes me annoyed most is when a driver is inconsiderate to others on the road. I can't stand a driver who is not willing to let someone pass when the lane is ending. I drive a truck and it amazes me that some drivers don't realize that if they hit me i am not going to get hurt because my truck is big. I am very patient 99% of the time when i am driving but then you have these drivers who make me really annoyed and wish the cops would stop them.
