And better enforcement to reduce large speed differentials (which I think are worse than the absolute speed in itself).
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.
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.
Are you saying you don't believe increasing the speed limit on the 401 will increase the speeds?
The reality is we will not get photo enforcement, nor sufficient police enforcement to actually enforce speed limits. Any discussion of actual policy must accept that this is not part of the plan.
