I think auto infrastructure should be designed around lower steady speeds with roundabouts and stop signs and lights, at least in the US. Right now we have high speed limits, wide roads which encourage speeding, but a lot of stop signs, long stop lights and driveway filled stroads that are terrible for everyone.

I'd like narrower lanes, bump outs raised intersections and crosswalks to slow traffic. Reduce curb cuts and driveways to cut down on conflicts - thinking Dutch style access streets and alleys that connect to the less interrupted travel lane.

The added benefit of lower speeds would make it safer for bikes and pedestrians and reduce auto crash fatalities.

Slower steady speeds would reduce stooa go, dropping noise and particulate emission from acceleration.
