</span>tl;dr: As a lot of others already said: a quite subjective thing to<br>
map.<br>
<br>
In Germany a lot of more experienced bicyclists regard all separate<br>
cycleways or even footways with bicycle=yes as hazard – with good<br>
reason.<br>
Every year a signifikant number of bicyclists get right-hooked by cars<br>
turning right and their drivers not paying enough attention.<br>
Every year, a signifikant number of those right-hooked bicyclists die.<br>
<br>
Never mind the cars parking on the cycleways, crossing service streets,<br>
the pedestrians, dogs etc which would make the experienced bicyclist<br>
cringe from awe while the less experienced are happy to cruise along<br>
with walking speed even on sidewalks where they are not allowed except<br>
being ten or younger.<br>
<br>
Ridiculous is the mentioning of snow or shattered glass. During winter<br>
and below 0°C common sense should tell a bicyclist that surfaces might<br>
be covered with snow or ice and thus slippery.<br>
Some tags regarding winter servicing do exist although the proposal<br>
wasn't guided to a voting process.<br>
For glass and other stuff on highways: everybody should expect that<br>
on the surface of the road stuff may lay which can harm the vehicle –<br>
from glass of bottles thrown away by stupid people to shattered windows<br>
of a car after an accident to nails and screws falling off carpenter's<br>
car to vehicle parts lost while driving (exhaust, bump guard,<br>
suspension parts, oil etc).<br>
Bicyclists may take into consideration that on a road frequently<br>
traveled by cars the smaller stuff like glass gets cleared away by the<br>
crumbling effect of the car's tires so that cleaning is in opposition to<br>
a cycleway needed less often. (Of course the bicyclist shouldn't ride<br>
to the utmost right of a highway were no cars go and all the rubble<br>
collects)<br>
