Then, on the sidewalk adjacent to Prospect Park, I describe the controversy over the Prospect Park West bike lane, which raised the ire of Borough President Marty Markowitz and some long-time (and well-heeled) residents of buildings along the block. I point out how, given the media megaphone focused on Park Slope, the controversy has made international news.
The visitors are generally incredulous. It seems a very reasonable trade-off to add a protected lane for bicyclists, thus narrowing a roadway conducive to speeding from three lanes to two. Yes, it may be less esthetically appealing to have vehicles park away from the curb and, yes, it may add a small degree of hazard for those crossing or parking/unloading. But, overall, it seems intuitive--and obvious--that the bike lane enhances safety.
There's still a lawsuit going on. (Update: It was finally abandoned in September 2016.) Below is a view of the "alarming" changes, via Gothamist.
