American driver education and testing are notoriously lax compared to much of the world; make driver testing more intensive and frequent.

Traffic enforcement is geared more towards municipal income generation and the facilitating of searches and arrests for other crimes than toward ensuring safe driving; stop pulling over poor people to search for drugs and start photographing and billing middle class and rich people for speeding or for idling in the middle/passing lane.

Car manufacturers jack up the price on critical safety features and make it difficult to retrofit them into existing vehicles; regulate them.

Our roadways are often designed poorly, mixing use cases in ways that result in unnecessary injury (e.g., "stroads" and intersections with poor pedestrian design); regulate and fix those.
