I'm reluctant to put a lot of confidence in the IIHS study. First, we're talking about changing the official speed limit, not actually increasing the 401 speeds. And better enforcement to reduce large speed differentials (which I think are worse than the absolute speed in itself).
Also, given the huge variations in enforcement, use of radar detectors and driving habits from state to state, I don't know how valuable their data really is.
Quote:The study concluded that a 5 mph increase in the speed limit causes an 8% increase in death rates on interstates and freeways. It causes a 3% increase in deaths on other roads.
