Running doesn’t (substantially, probably) increase the rate at which you shed the virus, though – so the droplets are spread over a larger area, at a lower concentration. You need to keep a greater distance to guarantee zero exposure, but that doesn’t mean that higher speeds equal greater risks. The car analogy is inappropriate.
