The best defense is simple. Follow the speed limits and drive safely.
Problem is the speed limits in most of vT are way to low for the area.
40 mph on Middle road in Milton is ridiculous, just to mention one
OR, is YOUR foot too heavy?
10 mph over the limit will NOT save you 5 minutes..
I have been doing work the Alaska Department of Transportation, it suks, but Speed limits are based on the most excellent driving conditions. (lack of a better adjective).
Clear asphalt........... Kick in the cruise control and pop in a Sinatra CD!
Snow and ice.......... Kick in a classical music CD.
