Do they even teach this in driving school anymore? Or do they do it simply to annoy other drivers? I had to pass some young guy with a beard laid back with his flat bill ball cap texting doing less than the speed limit on a four lane matching a 18 wheeler next to him. I accelerated and passed on the shoulder.
It’s mentioned, that’s about it. Most people camping the left lane have a “I’m doing the speed limit, I can be in any lane I want!” mentality.
I have noticed people tend to move when I come up behind them in the truck. In the 300 and our van, they couldn’t care less and won’t move.
