No it is very common here.

Wheelchairs, like pedestrians, have close to a zero turn radius capability. A person riding a bike does not. So put some right angle turns close to each other, and some one can walk through with their bike, but not easily ride through. (Although it is a fun challenge.)

I get putting them strategically to gate places where bicyclists and pedestrians will mix. I don’t like when planners use them to gate road (auto) crossings – the auto should be the one slowed down, not me. Or at the very least, it should be equal.

I did a quick search to find some images, and found a site explaining that some of these types of gates ARE sometimes impassible barriers to different types of bikes, bikes with trailers, etc, and there are better ways to slow bicyclist speed at an intersection.
