For real. In Iowa it's not TOO bad. Mostly though because traffic levels are low enough, when there's a basketball or football game in town and traffic is tight, people here drive like total morons.
I drove through Memphis and the drivers there are completely insane. I saw people doing like 100+MPH, in lanes with huge potholes around overpass curves, so they were jumping 1/2 a lane over every time they hit the massive potholes. I personally don't mind driving at high speeds one bit; but I mean really, if the road is so bumpy your suspension can't keep the car in the lane, you should probably slow it down! They were at least in the leftmost lanes, the traffic in right lanes was "only" doing like 80 or so. They were actually calling in the state national guard to start writing traffic tickets. There was a pileup as I drove through, and it didn't even make the local news -- they have so many a week they don't even mention them unless it has at least 5-10 cars involved!
Rochester, MN is probably the worst drivers I've seen anywhere, period -- people'll speed up by 20MPH to CUT OFF people trying to merge onto the highways there! You CANNOT signal a lane changes there, whoever is in that lane WILL either brake or accelerate to block out lane changes (not like "oh, there's 1.1 car lengths here, let's squeeze in -- they'll do that even if there's 5 or 10 car lengths open!). And even if it's someone wanting to move right to exit; you'd think people'd at least make it easy to get OFF the highway so that car will be out of their way! Just given those two restrictions alone you can imagine how people drove there. Oh, AND they run bumper-to-bumper and tailgate even in snow (even when there are other lanes with light traffic -- since, after all, that light traffic WILL try to cut anyone off that tries to change into the lane.)
