Lorenzo, I think you're doing it wrong: if you have knowledge about motor sport and feel the need to document a tag for those, good. Now there is a lot of sports where people 'race' in a wide range of facilities. Trying to get a one size fit all tag for everyone of them, including those you have no clue about is deemed to fail: either it will be inappropriate for corner cases or so general it won't be useful at all.
Now for motor sports, what is the added value for racing=motor_sport when there is sport=karting ? I'd let this to data consumer. See what happened with the 'piste map' page. Initially this was a documentation for the piste:* tags and skiing. Then it was naturally extented to other winter sports. But it doesn't summarize all winter sports, some being constantly added in OSM as a new sport=* value on a variety of features without the need for a new tag categorizing them within a 'winter_sport' set.
