Yes truck drivers have a tough job. That doesn't make them all good drivers. I've seen more than a few complete yahoos behind the wheels of semis.
What I'd really like to see is semis in the US designed more like the European semis. When I drove in Italy, the trucks were well equipped with aero aids, and generally designed to a have lower center of gravity than the trucks here. They also appeared to have pretty strictly controlled speed limits, significantly lower than the limit for smaller vehicles; every semi I saw in two weeks of driving in Italy was in the right lane, and moving more slowly than my little 1 liter Fiat - which was far from the fastest vehicle on the road!
