I'd think German traffic engineers could come up with a better solution, yet these are everywhere:
The bike paths themselves are desire paths for cars and motorcycles.
To block them off, they put up barriers, but those also block cargo bikes, wheelchairs and strollers, create a collision hazard, and force all cyclists to stop and dismount for no reason.
Of course, they'll be bypassed wherever possible โ naturally by cars and motorcycles too, if there's enough room.
I'm aware.
It's to force cyclists to dismount (which by the way isn't possible for all vehicles allowed on that path), instead of forcing cars to stop by changing the right of way.
