> it's still significantly safer than the taxi driving you to the airport. That's a bit of a myth, or a misunderstanding at any rate, as far as I can tell. Jets are much safer than cars per passenger kilometre - so for a given distance, you're better off to go by airliner than by car. However, per vehicle hour, fatality rates are the same order of magnitude (plane is actually 3x worse). So, if you take a 1/2 hr cab ride to a several-hour flight, you're more likely to die on the flight. Source: https://www.uber.com/elevate.pdf, p. 17 |

Btw, neither measure is very good for comparing cars to planes. Airliners carry many times more passengers per kilometer, on average, than cars do; and cars take many times longer to complete a route than airlineres do. If we are to assume that the probability of dying rises the longer you travel then obviously the vehicle that goes faster will have a better record... except of course for the fact that going faster may kill you faster too. Then again, it doesn't make much sense that the probability that a given person will be killed in an accident should vary with the number of people in the same vehicle as them!
Overall, what you really need to know to decide whether one or the other type of vehicle is safest is the probability to be involved in a serious accident given that you board a vehicle of that type. I don't think there's a good way to measure that, so measures like the ones above are just proxies, I guess. Which leaves them open to some degree of exploitation from industry bodies, that can claim that their vehicle type is the safest, even if it's really just a matter of perspective.
