Category:Stock car racing non-empty soft redirected categories

soft redirected categories should not be populated. Members of category redirects will be recategorized by a bot (eventually).

Category pages are added to this category by Category redirect. The categories should in theory be non-empty but may often be empty in practice due to caching. An empty category can usually be removed by making a null edit on its category page. This has to be repeated for every empty category. It will eventually happen automatically at an unknown time.
