[talk-au] Practicality of mapping high-speed motor-traffic routes as cycle routes

It’s certainly true that some people rely on motorway routes (I agree that the solution for family-friendly routes would be a different renderer, until conditions change in Australia). However, regarding the bike symbol on the M2 on the Mapillary example, it’s designed to be a sign of caution instead of a route guide (https://www.rms.nsw.gov.au/documents/business-industry/partners-and-suppliers/lgr/cycling-aspects-of-austroads-guides.pdf <https://www.rms.nsw.gov.au/documents/business-industry/partners-and-suppliers/lgr/cycling-aspects-of-austroads-guides.pdf>).

However, although cycling on the motorway shoulders is neither recommended nor common, it’s been mapped on OSM as the cycle route „M7s" (https://www.openstreetmap.org/#map=18/-33.83065/150.85767&layers=C <https://www.openstreetmap.org/#map=18/-33.83065/150.85767&layers=C>) along with the „M7 Cycleway“ route.

Although this seems to be a common approach for motorways/other high-speed roads in Australia of which cycling is allowed on, I can hardly imagine it to be of any practical use (i.e. providing convenient and safe connections for people cycling).

Although cycling on most motorway shoulders in Australia is technically permitted and commonly done by the very few “strong and fearless” people (only ~1%, as indicated in past transport research), it’s both subjectively and statically quite unsafe, which gives no use to most people when rendered on tiles such as OpenCycleMap.

>> Afterall, these “routes” probably shouldn’t be mapped at all, since they aren’t much use to most people; tagging them with ‘cycling’: ‘designated’ and ‘cycleway’: ‘shoulder’ would be sufficient enough. What do you think of this solution?
