Risk: car collisions

Elimination: no cars, walkable cities

Substitution: trains, buses, alternative transportation

Engineering: highways, sidewalks, traffic lights, bicycle lanes, school zones, speed limits, DUI tests, etc

Administrative: driving licences, road safety campaigns, law enforcement, vehicle attention / lane departure / impending collision alerts

PPE: seatbelts, helmets, crumple zones, lowered vehicle centre of gravity

We went all in on the least effective measures, and most of them only benefit the driver of a car, not pedestrians or cyclists
