If think it is scary out there driving your RV's spend some time on a motorcycle...I do both.
One thing I have noticed is folks will do just about anything to get around my 24' Class C regardless of my speed largely because they do not want to follow me. I understand that my large box is difficult to see around and this can be annoying to some. The fact that I understand their motivation does not change the degree of stupidity they exhibit to get around me at any cost.
I stay to the right and anticipate what is happening well ahead, how many times do you see these chuckleheads staying in a lane that is posted as closing ahead only to jam over at the last second just so they can pass 3 more cars.... ARRRRRRG!
IMHO: As far as deaths and injuries declining over the last years that is a reflection of the higher quality safety features and better construction that the modern vehicles bring to the roadways and NOT an indication that folks are driving better.
As always.... Opinions and YMMV
