This is a new argument and unrelated to our previous discussion.

Roads are communal and public. They may travel through communities, but they are not for the exclusive use of that community. This argument especially falls apart when looking at major thoroughfares such as Brattle. Why should the residents have any more say over those.roads than the people who use that road? There are many Cambridge residents that bike, walk, and scoot through that area daily. Why is their safety secondary to the concerns of the community on the road (concerns, which I may add, that are trifling compared to the daily threat of serious injury or death faced by vulnerable users of that space.)
