This - never happens.

I could see that maybe working if, and only if, the rack were set away from a building so bikes could be parked on either side, however almost all cases of that style I've seen the racks are set up along a wall, thus blocking one side from use. The other thing stopping those from being used like they claim are bikes with wide handlebars, like both of mine. I Have touring (butterfly) bars on one bike and the other bike is a dutch style bike with wide city bars. I park in one of those and my handlebars often cover quite a bit of space.
