Here are a few examples for you:

Nearby motorway:
maxspeed=none
maxspeed:hgv=100
maxspeed:(22:00-06:00)=120
maxspeed:(22:00-06:00):hgv=80
maxspeed:wet=80

Nearby pedestrian area (I will try to get a picture of the signs for this one for educational purposes):
access:bicycle=yes
access:vehicle:(weight<10):(Mo-Fr 06:00-11:00; Sa 06:00-10:00):delivery=yes
access:vehicle:(19:00-10:00):destination=yes
access:vehicle:taxi:(Mo-Fr 20:00-10:00; Sa, Su, PH 20:00-11:00)=yes

But as I also don't have the perfect solution in my pocket I will not oppose it. However I hope that no solution is approved and instead the discussion is restarted and kept alive until a good solution is found. I hope it but it doubt the latter.

Well, if this proposal fails I would say everybody who voted against it has to come up with a better one (where "better" is based on some actual arguments), but I do not believe in Santa Claus either. What probably happens is that this discussion dies, and people will either use this proposal (as they have done before) or use the note and fixme keys (as they have done before).
