Since 2000, I've led visitors around Brooklyn, and my two most fundamental tours, Brooklyn 101 and Brooklyn 202, go through Park Slope and cross Prospect Park West, usually at the Garfield Place stop light. When we cross, I advise people to look right and left in case bicycles approach.
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.
