Somethimes we tag bicycle=yes in case of routingproblems.
f.i. in case a route is crossing a road with bicycle=no and you have to traverse 5 m
On that 5m element we will remove the bicycle=no  or add bicycle=yes to make clear to other mappers this is an exception.


If you have questions you are welcome.
