How to Map
Applies to nodes and areas.
|amenity=car_sharing||Generic tag for a car pooling station / area.|
|operator=*||Name of operator (e.g. "StreetCar", "Zipcar")|
|website=*||Website of car pooling operator, or their sub page about this location|
Some car pooling operations do not have true reserved parking spots. At present there is no good scheme to map the acceptable pickup or dropoff locations.
