I don't use any mirrors, but I am aware of vehicles behind me by sound and/or headlights. I guess I prefer to concentrate on holding a safe line as far right as possible instead of checking a mirror for something I can't do anything about.
Two things always stressed in commercial driver training are "get the big picture", and "leave yourself an out". Whats behind you is 50% of your riding environment, being aware of whats behind you gives you more options to deal with whats in front, and besides you.
personally I find hearing to be my most limited sense when riding at anything above a walking pace due to the wind, and the noise traffic makes.
