The difference in traffic speeds among states with 65mph limits as compared to states still in the dark ages with 55 mph limits is about 2 mph. Oddly enough, when the limit rises, the slower drivers speed up and the faster ones slow down, so the end result is enhanced safety, fewer lawbreakers, and smoother traffic flow. - Join the NMA! $29/yr. 800-882-2785 National Motorists Association BYBL43A@prodigy.com
