Deletion of Keir Millar

Comment: http://www.independent.co.uk/news/uk/home-news/keir-millar-11yearold-stock-car-racer-dies-after-crash-10243081.html all articles are referring to him as a world champion. Are they incorrect? Even if it's only world champion in his age group, it indicates notability that goes beyond one event. Additionally, deaths in athletics (even motorsports) tend to be notable and are not considered
