|Definition:||A specific tag for (motor) vehicles racetracks|
The highway=raceway tag is designated to map the racing track itself and there is no tag suitable to map the racetrack in the whole, including raceways, boxes, spectator space, etc.. According to the actual wiki page it is possible to use this tag on areas when the track is not recognizable for some reason. We might consider to use it on the whole area but this produce the undesirable effect that is impossible to distinguish the vehicles designated area from the other, considering that the track itself could be drawn as an area where it is large enough.
This is a list of actually used tags.
- The related wiki page suggests a distinction from this pair and area:highway=raceway letting assume that the first is usable for the whole area but this not convincing and neither accepted by the mappers. There are problems with rendering because there should be color distinction and maybe it's not clear what object should carry primary attributes (name, contact info, ...).
- This seems to be the more used, probably because of the term and for rendering reasons. Its use is however for tracks themselves that are usually inside other facilities like stadiums and sport centers. Moreover the related wiki clearly says that it's for non motorized sports, indeed it can be considered the highway=raceway counterpart for such sports.
- Maybe this is the one that better suits for the purpose and it is widely used but in the wiki there is no mention on possible usage for places where motorized sports take place. Using this tag imply to map very different plants in the same manner and the only way to distinguish them each other is relying on the sport=* tag, that is probably not the best because it's pretty common to use not documented and also multiple values.
- This seems to be widely used probably for rendering reasons but its usage is for single playing fields and clearly not suitable.
The table below shows usage numbers obtained with Overpass Turbo. It's just for reference, only ways have been counted and some tags may have been used for both the track or the whole outline.
|Tag||In the same closed way together with sport=*motor/motocross/karting|
- There is a mention only in this talk and rarely used.
- This tag has been proposed but rejected 
- Applies to all facilities where motor sports take place. There must be at least one track on the ground for racing vehicles.
- Related documented sport=* values are motor/motocross/karting/rc_car.
- Do not applies to this sports but may be applicable if in the same facility are used also motor vehicles.
- For some other non-motorized sports there are cases where it could be applicable but they are out of this proposal.
- Animal or animal pulled vehicles. See also leisure=horse_riding
- Downhill with non-motorized vehicles
The preferred mapping mode is as area, which should include all permanent parts of the plant. Alternatively it is possible to set a node as a landmark and apply the leisure=racetrack tag to it. Add to the same object the sport=* tag with designated values separated by ';' if more sports are practiced. Add name=* and other usual tags.
The track itself inside the area has to be tagged with highway=raceway. All the other tags already used on the outline way should not be replicated here. The sport=* tag may be considered optional if the value is the same as the outline area. If a racetrack includes more than one track in which are practiced different sports, it is required to add the sport=* tag with the specific value(s) to every track. The name=* tag can be used to add a specific name to a track if it has or to name the various parts like turns. See the dedicated page for other details.
Transition to the new tag
Alter what is already mapped would mean losing immediate visibility until the tag is accepted and become of common usage, anyway the actual mapping way is very diversified and often incorrect so not easily accessible.
racetrack or race_track or what?
The English wikipedia page for Race track suggests this words and others. racetrack seems to be the more suitable but suggestions are welcome for other terms which could better designate the feature.
The same as sports_centre and stadium.
