That's never been my experience at all, and Brookline is my home town. I have no problem hating on the fact that Brookline people are entitled, generally speaking, but I have always felt safer biking anywhere in Brookline than anywhere in Boston, or even Cambridge. First, there are tons of stoplights, and second, and more importantly, Brookline has always been a police state, cops everywhere who actually do constantly pull people over and ticket them. Even now, post-Floyd, with the nearly complete disappearance of speed traps, Brookline continues the hallowed tradition of posting cars all over the place. Drivers in Brookline drive scared, and I have always felt that they were timid when it came to me on a bike. The parkways (as in West Rox, Newton St, and Grove St) are the only roads where this is not the case. Despite my earlier comment that Washington needs a road diet, I've never felt unsafe there nor do I consider it a road where people speed.
