"But for a car it isn't fun to be caught behind a big slow driver on a two lane highway. On a freeway I can always pass without worrying about oncoming traffic."
I drive 55 to 60 mph on state and US highways. If I get cars behind me that can't pass due to traffic, I will pull over after a couple of miles. While driving across SD, ND, WY, or MT there is usually no traffic to worry about so people pass me without a problem. Why do some people feel that it is a sin to drive slower than warp speed?
Here in Wisconsin the speed limit on two lane roads is 55. I do the speed limit without problem. The speeders can get by me when they find a passing zone. I don't worry about them at all. I get flipped off once in a while but I just ignore at them as they go by. No need in setting off some road rage moron.
I avoid the interstate because the speed limits run anywhere from 70 to 80 mph. I don't drive that fast.
