There has been a lot of hoopla about the new bike lanes on the 3/4 of a mile of Comm Ave between Allston and Kenmore Sq and they are a welcome addition to the city. Now it looks like we need some traffic enforcement. Predictability is one of the most important factors for safe roads for both drivers and bicyclists to be able to anticipate what will happen on the road. Cars parked in the bike lane force the bikes to swerve in and out of traffic - a situation that could be more dangerous than having no bike lane at all. So hopefully drivers will learn - with help from some parking tickets, if needed - that bike lanes are for bikes, not cars.
