Juan Taco wrecked due to a mechanical breakdown.
Last I checked you fight the fire at its source, not where the fuel is going-in this case at the apron.
The crash on lap 2 took out TWO Felony Motorsports (Hendrick) cars-Mini-Me (Johnson) and Danican't. Yes, I know she drives for SHR but it is only a Hendrick satellite op. Hendrick cars, engines, engineering, they even swap pit crew members.
