It's more like 'what scares you most' while driving. If I get ticked off, and respond in kind with aggression, I'm just escalating the situation. I try to stay calm and get the heck out of their range.
one of my pet peeves is (ask my kids, I'm always griping about it): drivers who don't signal their turn until after they've slammed on their brakes and have initiated the turn. jeeze- the whole point of signaling is to warn the person behind them so they don't have to slam on their brakes and ruin their mileage
another scarey one is people who tie things on the top of their car with dental floss and then go out and drive on the highway at 'normal' speed; aka huricane force winds!
saw a mattress this past weekend that was gonna go soon! it was a foot off the roof of the car in a nice aerodynamic curve and the guy was doing 75 in the passing lane! yikes!
got hit by a big inflatable raft once- I had just moved out to pass the guy and get away from him, and he pulls out right in front of me to pass someone else, and the damm raft came loose right then and sailed back and slammed into my windsheild! yow!
