How about the increasing number of people who have NO IDEA of how to merge into a highway from an entry ramp?
I pretty much always stay in the right lane when I'm towing, because as others have noted, I'm the slow guy at 60 to 63 MPH. Well all bets are off when a group of cars is entering from a ramp. I used to try to slow down a bit to give an entering guy a bit of a break. But I've discovered that this is more confusing to some people, and they slow down too. It doesn't do any good to signal (with hands or light flashes) to let them know to enter. But then I've had people give me the finger and the evil eye if I DON'T slow down to let them in. They have complete control over their own speed. They can get in front of me or drop back to go in behind me. But they're on the verge of road rage because I won't let them in????
I attribute it to the fact that the skill of entering a highway is not part of the road test for getting a license. I wish it were.
