Glen: We can tag as the proper track:
I checked out Indianapolis Raceway and it is a highway=raceway and lesiure=track. Adding the sport tag as well.
HB: download preview showed that type=0.0, fixed that. now ready to go AFAICT.
Added area=no as this layer is the centre-line of a course, not the bounds of an area. (leisure=track makes it be treated like an area)
