If ##% of commuters exceed the limit to get to work, and they are forced to cease, then the time and highway space they save speeding would instead be added to the overall stress of traffic. That would have ripple effects against people who drive the limit, and would cause everyone to need more commute time. The question comes whether the added stress would be debilitating for other commuters.
Edit: I'm a _very_ conscious and aware driver, and agree that driving fast is dangerous for many people. It's an unfortunate situation we're in, where the busted family wagon must defend against the drunk loony in the sports car. Sometimes however, the drunk loony in the sports car has to defend against the family that's fighting inside the wagon.
