In the early 1970s, disability activists in Berkeley, California poured concrete ramps into street corners at night so wheelchair users could cross.
Cities eventually made curb cuts standard. Then something happened that nobody had planned for. Parents with strollers used them. Delivery workers with carts. Travelers with suitcases, cyclists, kids on scooters, anyone with a bad knee. A fix designed for a few turned out to be good for everyone, and the pattern got a name. The curb-cut effect.
Smoke-free spaces run on the same physics.
A park or a workplace goes smoke-free for the people with asthma or the person three weeks into a quit. Then the air is cleaner for the kids, the workers, the grandparents on the bench, the person who never gave it a thought.
Nobody loses a curb, and everybody gets a corner they can use.
