This does not imply we should ignore the others, but we must not invent tags for hypothetical transport modes unless they are needed somewhere.

It certainly is doable for standardized signs, but many jurisdictions allow for free form signs (text), so this can never become "complete". See 6.), lets discuss and invent new tags when needed. I've suffered myself from unclear textual traffic signs, at the via Appia Antica in Rome (ancient road with paving that doesn't make it generally useful as a shortcut), vehicular traffic is generally excluded (in theory/by signage), but there's a textual exception: "except local traffic" (it:eccetto traffico locale). I've asked on the Italian mailing list and checked in the traffic law, but the term doesn't seem to be defined. A websearch only found other people with the same problem of not understanding the meaning. Here's an official example of the police ordering such an exception for a day (but there are also permanent signs): https://www.comune.roma.it/web-resources/cms/documents/disciplina_bianchi.pdf (you can see that they first added "except residents" and then changed it to "local traffic"). > > multi_tracked_motor_vehicle, the possibility of use, used in presets, (it > is a correct key) maybe over 10-15 years, we see, it is a established key, > more important then motorcar. ;-) The life of a key.

Something like "pedelec" and "speed_pedelec". It's probably only a question of time when the legislators will start to cater specifically for this kind of vehicle (own symbols etc.). We're supposedly in a transition phase where things have not settled yet. It seems also to be better according to your list (points 1-4). Cheers Martin
