After reading the article, I gotta tell you atleast a couple times a week, a driver pulls up beside me with his itty bitty in his hand and a big smile on his face.
When other trucks pass me, I don't look at the drivers, simply for that reason.
These guys are usually on the horn, or swing over really close to me, something to get my attention.
Basically what I'm trying to say is, this is a very common problem that goes on more than you know.
