For grad school I drove from PA to Texas, then up through Canada and back into the US via Buffalo. The states I drove through were PA (obviously), West Virginia, Kentucky, Tennessee, Arkansas, Oklahoma, Texas, then up to Canada via Oklahoma again, Missouri, Illinois, Indiana, and Michigan. I had no problems with any of them other than maybe Texans speeding constantly. Canadians drive very, very well.
I went to a Metallica concert in East Rutherford, New Jersey two years ago and I wanted to blow every vehicle off the road. No turn signals, cutting in and out of traffic, people aggressively shoving themselves into your lane, giving the “thanks” wave and assuming that means they can merge at will. Awful drivers all around.
