Is It This Bad Elsewhere? How Do People Drive Where You Live?

The other day, I was driving on I-44, and traffic was pretty heavy. I'm in the process of passing a line of several vehicles, and behind several. Some idiot comes up on my tail, and starts flashing his lights at me. I don't know where he expected me to go. Couldn't get over, and couldn't go any faster. Finally pass all the rigs, and get over. He goes flying around me, up on the next car, then switches lanes behind another car. He does this leap frog thing for about 3 or 4 miles, then takes an exit. Did I say idiot?
