I replaced the useless mirrors on my 'C' with trucker's mirrors so that I could see along either side of the 'C' from the driver's seat. And I stay in the right hand lane, so anyone trying to pass me on the right would have to do it on the gravel berm. I also set the speed control 5 MPH below the max speed limit and let everybody pass me. I wave to them as they pass me, and sometimes, they return the wave, only some don't use all the fingers on their hand.
I also limit my driving to after morning rush hour and before evening rush hour. That also gets me into a FHU RV park early enough to pick my site.
Being retired helps a lot.
