I just love the cars that match us for speed when they are coming up the ramp. They run out of room and think they will just duck in back of the motorhome. Then they realize, we are towing the car behind us.. No way they are going to sneak in between. I have taken to watch them in the side rear view mirror.
Most of the time, a speed adjustment on their part would have allowed them to merge without a problem.
As far as they are concerned, they are the only ones on the road and everyone else should get out of their way.
When we can, we move over but with semi trucks on your left, you just can't do that for every idiot. It's in every state.
