The database as well as the presentation of bicycle traffic is quite insufficient up to now:

The carriageway of many residential streets is a one way street for motor trafic but legally bidirectional for cycle trafic. In the specification of accessability, I have started to edit “cars - yes” and “biycles bidirectional”. When and how will this be visible in the mapnik?

In some countries biycle tracks along streets are compulsory, in others you may use them but it is not forbidden to cycle on the carriageway (what has proved to be much surer at intersections, where most accidents accur, in cities and villages).

Countries like Germany have started to distinguish compulsory and facultative cycle tracks. I have started (I hope, not only me!) to edit on such cycle tracks either “compulsory” or “facultative” instead of “designated”.
