I feel for the truck driver as they are working and need to get to the job etc. A few years back I was traveling up to Door County Wi doing the speed limit and there was a logging semi behind me. He was just not happy with me going to speed limit, he finially found a place to pass and boy did he there was no speed limit for him.
This year I traveled up I70 in CO going east and many many years back I remember semis moving all the way over to the right shoulder to help keep the other semis moving at good rpms. Boy this does not happen now I had to slow down once and thought I would never get the rpms up.
So my point is the world is changing, sit back and relax. We may not like what we see but then do we really know the reason.
