Jimmie Johnson is the 1st NASCAR driver to test positive for COVID-19

"It's a test, it's a tryout and it's a two-way street. Two-way tryout for the team to look at me and for myself to look at a team," he said. "If I'm about four seconds off the pace, then that's probably a quick sign that I don't need to be in one of these cars. If I'm within a certain amount of time and I have a good feel of the car, then for me, I feel like that's an important first step that I need to know that I can be competitive.
