@jwz additional context as this is getting boosted: Pedestrians (particularly those using mobility accommodations like a knee-walker, wheelchair, etc) are the most vulnerable users of a traffic system. We have no airbag or exterior frame that will protect us in a collision. Further the infrastructure in America often works against us. Cyclists don't fair much better. The onus of safety responsibility should be on policy makers, traffic engineers, & the people who are operating multi-ton vehicles
