I'm in central Oklahoma and must agree with Paperer - pokie-Okies are always cruising in the passing lane on the highways. I don't see much improvement in the cities though - if there are 2 people on any given stretch of road, they are driving side-by-side 20 MPH under the speed limit.
I'm not sure, but brake lights and turn signals on trailers may be illegal here. If I ever see a trailer with lights, I'll ask the driver and report back.
