Urban planning that separates pedestrians and vehicles.

Roads that are narrow in places where a lower speed is desirable.

Heavy taxation on vehicles with more mass and lower visibility.

Actual licensing standards other than driving down a couple of city streets and parking.

More crossings, with lights or bridges, instead of long four-lane arterial roads with nowhere to safely cross.

We have most of that in <pick some European city/country>, and the statistics show it makes a big difference compared to the USA, but drivers still exceed the speed limit, run through red lights etc and cause injuries and death to pedestrians and cyclists.

Removing automatic enforcement of speed limits would not improve the situation.
