[talk-cz] Tramtrack and highway

Hello,

((TLDR: yeah, why not; are there enough relevant cases though?))

As your examples show, there are two different usages here: the more common
one (first two attachments: Vítězné náměstí and Podbabská) is a public
transport stop where bus lines and tram lines serve the same platform. This
is not intended for general traffic, not even for buses as a vehicle class,
and should be tagged as such (e.g. access=no, psv=yes). This seems correct
to me, as these are special roads that aren't for public use anyway.
(Similarly for tram tracks that are technically drivable by road vehicles,
but only emergency services are allowed to). Do you also suggest to remap
these into separate ways?

The other case is, IMHO, an actual case of outdated mapping, and something
that could be fixed in a challenge. I think those are a minority, though -
is it worth the effort to set up a challenge for these?

Classifying one or the other (if tags are missing) would probably require
OTG resurvey: I don't think this can be reliably decided from map data
alone.

Best regards,
Honza "Piskvor" Martinec
