Hi everyone!
Just a quick question: I’ve seen quite a few parking lot / garage ramps recently but I could not find any information in the wiki on how to represent them. Do you know how to tag them?
I’m talking about those narrow, steep ramps that are commonly found in multi-storey parking lots, underground garage entrances, and so on.
In the case of the underground garage of an apartment complex, it doesn’t make sense to draw any parking lot or mark it as parking lane, so is it highway=service then?
Thanks in advance! 
Personally, I only map the external roads as highway=service + service=driveway, terminating at a Tag:amenity=parking_entrance - OpenStreetMap Wiki where it enters the parking building.
I don’t map the internal roads / ramps at all.
