Ah, well, I happen to live in the Dallas/Fort Worth Metroplex which, according to a news report I heard a few months ago, has the rudest, most aggressive drivers in the United States.
And that is true, I'd say. I find it dangerous to be in a car, much less on a bike. There is a ME ME ME attitude that is very troubling. The road belongs to ME! Get out of MY way! I'M in a hurry! I get to go the fastest! This is MY lane! I WILL ride your bumper as long as you are in front of ME! I WILL change lanes at high speed and come within 2 inches of your bumper! I AM SO IMPORTANT AND you ARE NOT!
And if you don't immediately submit to another driver's whims, then they will go into an uncontrolled rage and you can see them going spastic gesturing and bouncing up and down in their seat and yanking their car about in the lane. Sometimes they shoot at you.
Sometimes they're a good shot.
I'm not kidding. Serious power and control issues on MY roads!
