My god do I wish they would enforce the law in Oklahoma! The entire state seems to have a culture of pulling into the left lane then hitting the brakes and pacing the slowest thing moving in the right lane. People look at me crazy when I start ranting about Okies and their driving habits but give me an hour of freeway time and I will make you a believer. If you are anywhere near Oklahoma and someone is clogging up the left lane, chances are they have Oklahoma plates. I used to think it was related to their stupid football rivalry with Texas - when I drive through Oklahoma with Texas plates I got a lot of beer cans thrown at my car and people yelling some football slogan at me, but I’ve also driven through with New Jersey plates and Vermont plates, and it doesn’t matter - you might as well add 90 minutes to your travel time because everyone from Oklahoma drives ten miles under the limit in the left lane. So fire up your dash cams and take the Okie challenge, drive through Oklahoma/Texas/Kansas/Missouri/Arkansas, if someone is clogging up the left lane then try to get a look at their plates, will be Oklahoma the majority of the time.
