The only two things that bother me about OK driving is 1) the way they cut corners. You are getting ready to make a right and have to watch for the guy making a left turn from that road. Apparently there is no such thing as a 90 degree angle here. And 2) they don't yield when they are supposed to.
The only things I don't like about California driving is everything.
The only driver worse than a California driver is a Texas driver. I see a driver do something incredibly stupid and I look for the Texas plates. Or, I see Texas plates and I slow way down and get the heck out of the way. Sometimes I then count the seconds before they do something stupid.
It's usually in the single digits.
