City Councilor Sal LaMattina says it's time to consider regulating Segway use on city sidewalks. Matt Conti posts a copy of a request from LaMattina for a City Council hearing on regulating the dorkmobiles, which are an increasingly common site downtown and in the North End. At least one company even leads Segway tours, which Conti writes have become so prevalent that they are beginning to cause pedestrian issues.
