I don't need to slow down because I'm not exceeding the posted limit. I also don't need her sign in the road because speed limit signs are already posted throughout the neighborhood. I have no problem with the police monitoring her street for speeders. Our local police have plenty of time to make sure nobody commits a rolling stop at any of the twelve dozen stop signs in our neighborhood they can surely use part of that time to catch speeders so Karen can go back to not watching her children.
