It feels like this infrastructural risk is media driven to the extent of "pedophile kidnappers" or "razor blades in apples". For example I grew up in an Eastern MA "suburb" in the mid 90s - early 2000s, characterized by narrow winding roads, fast drivers, and no streetlights. Everyone too young or unconnected to have car access bicycled or walked everywhere; parents were a bit fearful but ultimately acquiescent ("better dead than dumb, and if you're not dumb you won't die"), and cops only cared about trespassing with intent to vandalize.
Over the intervening years, the town added nice wide sidewalks (previously none), fancy crosswalk infrastructure, lighting, and started enforcing speed limits extremely aggressively. Yet the number of people on foot and bike dwindled to almost nothing and now the only ones are older middle aged folk walking their dogs.
