My point exactly. Car drivers you can and do see. Really hard to see what a truck driver is doing. Accept the fact that most are professional, but are affected much more by driving conditions such as heavy loads, wind gusts, bad roads, all while trying to watch out for idiots in both sides, and the ones in his blind spots directly behind and on both sides. Add to that driving a straight shift with up to 13 gears, limited power and acceleration, and is outnumbered 10 to one by the most important people in the world. Take a Defensive Driving course!!
