Road safety activists and some states are pushing to depart from a longstanding rule that sets speed limits in the United States based largely on how fast drivers actually travel.
On an interstate (all on/off ramps, no intersections, clear of pedestrians), that would be fine in terms of safety. The road would take more wear and tear, and gas millage plummets. At a certain point, the curves in the road don’t sweep gradually enough for all types of cars and trucks to handle it. If designed for it, 150mph can be done safely. The German Autobahn proves it.
When you have intersections and pedestrians and such, things are different.
