I'd like a better source for that information than Uber, as I'd like a better source for the information on the safety of air travel than air carriers.

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.
