My wife and I have been residents of the Back Bay for 20 years. Lately, we have on every occasion, when we have been walking about in the city, seen mostly young men, on unlicensed delivery scooters. They frequently drive recklessly on the sidewalk and streets, they do not obey traffic signals and I have witnessed several near misses with pedestrians and other vehicles. Since most of these vehicles do not have license plates, I assume they are not registered or insured. Some drivers appear to be too young to even have a driver’s license. Many also do not wear helmets Many of our friends have also told us that they too have witnessed this and do not understand why this concerning behavior has not been addressed. Why is the City (Police) allowing this dangerous behavior? On Boylston Street at Copley Square, directly across from the CVS, at anytime day or night, you will find many them of them congregating, just waiting to receive their next delivery assignment. I implore you to stop this before some innocent pedestrian or one of the young drivers is killed.
