I have had the same rv pass me 3 or 4 times in a single day, happens all the time. Bet they thought they were making good time! I spent over 20 years driving a truck, the only times I would speed up was behind schedule or trying to get to and through a city before rush hour. I got pretty good at planning trips, and those things rarely happened except for breakdowns and such.
I can't come up with a reason to rush anywhere anymore. I do sometimes drive well into the night still, just prefer driving at night because of the lighter traffic, but not in a hurry at all!!
