I see these every time a bicycle path intersects with any kind of car or train infrastructure. It just seems really patronizing, as if we’re not capable of slowing down without getting off the bike; it also shifts responsibility onto the cyclists if there is a crash based on something arbitrary (mounted vs dismounted).

Concur, same here. What gets me going is a sign saying cyclists are allowed to use the road. Think about it since years to put up an add on that says “cars too, but only on this road”. There’s such a thing as legislature and that already defines that we may bike on any road or except a motorway. So why the hell would someone patronize a normal road like that ffs
