If people speaking one language are more likely to see 4-wheel and 2-wheel taxis as variants than people speaking a different language. If true, I have absolutely no idea how this helps the list reach consensus about anything. :) Query tools are really important to consume data and my point wasn't to > downgrade tagging readability in general (nor to encourage K9842=V2179). > The taxonomy adopted by the person making the query will influence how useful that person finds the results.

If you use amenity=taxi + vehicle=* you guarantee that any carto which renders amenity=taxi will render ojek ranks incorrectly at first, and perhaps incorrectly for all time (if they decide they're going to ignore the vehicle tag). If you use amenity=motorbike_taxi you guarantee that all cartos will initially not render it at all, but that eventually some of them will (but you have no guarantee they won't then render it identically to amenity=taxi). I can't decide which of those two alternatives I prefer. -- Paul
