IMO, the worst drivers on the planet live in Ohio.
In the biggest town near me (Ft. Wayne), if there's an accident typically one of the cars is from Ohio. Of course driving in that city if you're not used to it can be confusing. The way some of the roads are set up, you have to wonder what the engineers were smoking when they designed them. There's a section of I-69 where the exit and entry ramp is at the same place! I kid you not!
