INDIANAPOLIS — Jimmie Johnson and his family took every precaution to avoid the coronavirus. They washed their hands frequently, diligently followed the face-mask guidelines and even left their home in Charlotte, North Carolina, for the less densely populated Aspen, Colorado. And yet both Johnson and his wife still tested positive for the virus this week — knocking the seven-time NASCAR champion out of what was expected to be his final Brickyard 400. Johnson is the first NASCAR driver to test positive for the virus that causes COVID-19 and it will end his streak of 663 consecutive Cup starts.
