I have never had any problems or incidents with commercial truck drivers but once you get in a large vehicle like an RV you start to realize how many people are driving little cars that really shouldn't be behind the steering wheel. Sometimes kind of wonder how they got a drivers license. They don't go with the flow of traffic, its gas brake, gas brake. I drove commercially in Los Angeles for a while and actually find that Los Angeles drivers are better than drivers in most other states. In WY no matter how fast you are driving drivers cannot stay behind you. They pass on hills, curves, don't think they understand why a double yellow is painted on the road. Guess that is why you see all of those markers in WY and MT where there is almost no traffic.
