A lot of people are required to consistently add motorcar tags to highways differently compared to the current documentation until the “few” can update the access page without an outcry or at least revert from the rest. This particular wiki edit is not the reason the motorcar key has different meanings according to its value, rather the other way round, the hint was added because it was used like this. And it was used like this because the same motorcar symbol on traffic signs has different meaning depending on the kind of sign (prescription or restriction), so there might be a perceived data inconsistency from the pov of a data consumer, but less so compared to real life. > They did not want to solve the problem then. they?

IMHO this is a completely different situation. Very few mappers own sidecars, personally I have no idea which specific rules apply to motorcycles with sidecars (or are you asking for bicycles with sidecars?), and as a result mappers tend to forget about adding sidecar tags (or are simply not interested in looking up the details). Each category cannot be dealt with equally on a practical level because people are volunteers and are adding tags about things they care for. Sidecars probably haven’t reached the point where there are enough mappers so that decent coverage could have been achieved. Look how good we are in representing bike access specifics, it’s because there are so many cyclists. > > “The meaning of tags”, is a key/value combination, both key and value must be > distinctive, so the combination can not mean something else, waht both say. > Contradiction must be avoided. That is common method usage. generally I agree, exceptions apply. In the motorcar example they are grounded in real life particularities (best reason I’d say). Cheers Martin
