Central Square is a wonderfully busy hub of commercial activity, and as such, it is understandable that there is a lot of vehicle traffic.
Alongside this high vehicle traffic is high bike traffic.
The large number of drivers and riders only means the chances of accidents increase when (and not if) bikers have to merge into the vehicle lane to get around a vehicle obstructing.
No one has ever seen TPTD really do any sort of bike lane obstruction enforcement even during the day when they're working - only parking.
Therefore, this sort of enforcement falls onto CPD, even though it sucks and is boring paperwork! CPD already has 2 Central Square units with the standard complement of route and sector cars, and now with the substation soon-to-be, lots of Central Bike units!
CPD, please encourage your officers, especially the CBs, who themselves will bike in the bike lane, to take an occasional bike around Mass Ave, and have cars moved along.
