Awareness is far more important than if you are doing 10 over as far as safety is concerned. People with their head up their a$$ cause far more accidents than people doing 5-10 over.
I wonder how long it takes you non speeders to pass a semi on the interstate? It drives me nuts when people just seem content to drive in a semi's blind spot for miles. There are a hundred things that can happen next to a semi and they are all bad. Pass the truck as quickly as possible, I assure you that is safer than waiting on a tire to blow or trucker to change lanes on you.
