Seniors walking for exercise in icey, dark winter nights in their neighborhoods; mothers pushing their babies in their strollers;  kids riding their truces and  bikes in front of their homes; people riding theirs horses on quiet side streets; people walking their dogs after work; wheelchair users- ALL are safer -- and feel safer - with speed bumps ( paid for by these residents) reducing some of the driving insanity and carelessness that kills and injured so many. The speed bumps keep the street "ownership" and neighborhood comity in the hands of those who live there.. I'm sorry if the bouncing in s speeding fire truck causes moments of discomfort for our supposedly less-than-fragile fire personnel -  but they are wearing helmets and belts, are they not? Not every neighborhood once the streets there kids play on or stroll along to be just another freeway!
