Even a worst-case scenario – an unusually large plow passing by a light, top-heavy sports utility vehicle at highway speed – could not generate the air pressure needed to cause the SUV to even visibly tip. A semi driving at highway speeds only generates about 1/6th of the air pressure needed to make this myth plausible.
