There are always a few bad apples and sadly Mr.Mark seems to have met one. Almost all the time I have found truckers respectful when I am on the open highway. I leave space for them, they leave space for me. I make it a point to hold back and open a space when lanes merge...whether in my RV or car. As for the turn signals, I just don't know what it is with people, maybe they just get involved in looking at "that big house driving down the road". I had one little red car hit me with the right side mirror because she was looking at the RV and turned the wheel along with her head.
