Only a very tiny minority of airline passengers are qualified to fly the plane. However almost all passengers are qualified to drive cars.
Quite honestly I have never ever heard of any car-driver ignoring regulations like speed restrictions or traffic lights.
And in the most unlikely event that there were to be a case of a driver with excessive drink/drugs in him with two passengers in the back who are not wearing safety belts, then the employer of the chauffeur can always say that the fatal crash was deliberately caused by the Secret Service.
