On Highways, speed limits are not necessary. In the city, they are entirely too low. They are set at 80% of the safe driving speed of a road in bad conditions. There is a road in Dallas that as you exit the Hwy, the road is 30 mph. Its even a commercial district. Total speed trap. Speed limits are set for money and not for safety.

Good point. I was once told that the Interstate Highway system was rated safe up to 100 mph, exception of course being mountain roads and through cities.
