You've seriously seen "dozens" of people killed?
I just sat back and tried to estimate (since of course, I don't have a CB in my car and can't follow traffic details like a trucker) but I'd guess I've driven past at least 5 fatalities -- and that's just fatalities I've noticed (body on stretcher, read about it on the news later, etc)
Emphasis in too long, because this is the reason why road signs announce dangerous sections of a road with even miles in advance.
