We had a speed limit enforcement day on I95 in NH during some holiday weekend (July 4th?) and it slowed down traffic considerably. They pulled over anyone doing 80+ (in a 65 MPH zone) and ticketed them. I believe it was about eight cars involved all day being fed the people to watch for from what appeared to be a disabled van they passed earlier. The state made thousands off of the Massachusetts drivers that couldn't respect our roads, everyone slowed down and saved gas, reduced emissions, and was safer. We all won
Anyways, we really do need to keep the speed limits low for the environments sake. If you don't like it, then I hope my state gets to collect from you so our road taxes remain cheap.
