Municipalities have learned to just ignore requests for speed bumps and traffic calming stops because the same people who ask for them will be right back in front of them next month complaining about noise and pollution from all the accelerating cars. That is a problem to which there's really no good solution that the town can implement. The net result is the initial complainers are still not satisfied and the silent majority who thought the area was fine the way it was are now annoyed by the stops or bumps. From a "keeping the townsfolk as happy as possible given the resources we have at our disposal" it's an obvious waste.
