Here's a shot of the Park Avenue pedestrian mall at 88th Street, taken by reader BicyclesOnly last night. Thanks to sheer luck, it appears as though no one was caught between the car and the light pole.
A few well-placed bollards could reduce the element of chance here. But recall that back in early 2007, Manhattan Community Board 8 deemed physical protection of these ped refuges too unsightly to support. Lately, CB8 has shown more of an open mind toward street safety measures. Maybe it's time to bring this idea to their attention again.
