> rough roads inflict costs in the form of reduced vehicle speeds.

Most non-rural places do this on purpose in concert with not ticketing noisy (eg - exhaust notes) cars and trucks. Really makes for a sadistic feel when noise machines are prevented from leaving the area quickly.

Traffic "calming" is another deplorable initiative. Nothing better than exerting ultimate control over the roads to sadistically keep them filled with traffic at all times so that peace and quiet never surmise.

And, people still believe they have the freedom to drive wherever they want, anytime they choose. Sure, but you're basically on a bus schedule now with all the added stops and flow control.

Say, can y'all figure out how to create road surfaces that actually dissipate noise (like blacktop), but not for a limited time or limited ideal operating envelope?
