As a side note, the only time I have ever made mistakes while driving that have caused problems has been when I was NOT driving agressively and completely focused on the driving (and usually not paying attention to the speed limit)

Its when I am out of my zone, in the right lane following everyone else, spaced out, when I start to have problems. It is not comofortable and it compltely throws off my senses to be travling as a sheep.

Or I can cite the past couple times that I have had my car ran into by people not paying attention. Sideswiped...twice...it upsets me more than anything.
