Excessive speeders in the absence of speed-limit enforcement just creates neighbors that don't mind their neighborhood being consumed by speed bumps/dips, I think there's an analogy here in residential areas. And if you have a lot of children in your neighborhood, there IS a 'xx-phobia' for speeders. But speed bumps and dips are an absolute nuisance and sometimes dangerous, so just having cameras identify and a system willing to punish speeders would absolutely be the preference.
