Have you ever driven a long distance instead of flying? If so you sacrificed safety for price / convenience - over the same distance flying is much safer. Are you driven by a professional chauffeur in an armored S-Class? If not you are sacrificing safety for cost.

You could imagine pushing pro-regulation arguments to absurd circumstances, like making it illegal to drive more than 125 miles (requiring people fly instead) or banning all cars aside from the armored S-Class etc. The side effects of such rules would obviously be very bad, but smaller regulations could have smaller, still deleterious consequences. See the case of unsafe cars in India: https://marginalrevolution.com/marginalrevolution/2016/05/sa...

I am absolutely not saying it doesn't happen. I am asking how can we tell?
