CHARLOTTE, N.C. — Kyle Busch says he supports wearing a mask in public so “we all can take care of our neighbor” amid the coronavirus pandemic, a rare instance of the two-time NASCAR champion wading into a social issue. The reigning Cup champion rarely speaks on non-racing issues, but Busch entered the debate after images from short tracks over the weekend showed packed grandstands with little social distancing and few people wearing masks. Busch retweeted a photo from South Alabama Speedway in Ozark, Alabama, and added his own message Sunday before the Coca-Cola 600.
