    Worth noting that the per-mile and per-trip stats are different. Planes have low per-mile rates because nobody sane is using a plane to get across town. They only use planes for long-distance trips where driving/taking the train isn’t feasible. So by default, planes will have low per-mile rates because virtually every trip is a high mileage event. In short, planes drastically water down their per-mile averages.

    When you look at it from a per-trip viewpoint, cars are safer. Which makes sense. You drive to work hundreds of times per year, but maybe ride a plane twice? So a single car crash is going to be a drop in the bucket when compared to the thousands of car trips you’ve taken in your life, but a single plane crash will be a massive spike in the numbers.

    I just wanted to point out how statistics can be used to justify either side. Lots of people want to rely on numbers for everything, as if statistics can’t be manipulated. But they can, and you can bet your ass that if a party has a vested interest in stats showing one result over another, a team of statisticians can figure out a way to make it happen.

      In 95% of all car accidents, the driver has eaten carrot in the week prior to the accident.

      you may now draw your own conclusion

      If you are considering two modes of transportation for a airplane-suitable trip, the per-trip stat is effectively irrelevant. If we consider a 1,000 mile trip and want to choose the safest manner of travel to the destination aircraft will statistically be the safest transportation method.

      Thank you, PM_Your_Nudes_Please, for an wonderfully insightful comment on the nature of statistics in transportation accidents.

      I don’t really agree. If I have two choices to make a long distance trip, drive or fly, it is safer to fly. If I’m going to the grocery store, there’s no option to fly, so using those type of trips in the calculation doesn’t make sense.

      If we talk about the safety of cars vs planes, we should really only be considering trips of a distance where planes are a viable option. Even then a trips per crash seems like a far worse metric than miles per crash. You want to account for complexity of the trips still.

      Do you have any statistics about the total number of miles driven by cars every day vs. miles flown by planes daily? Somehow, just based on the amount of cars worldwide, I’d bet that there are far more miles driven by cars daily than miles flown by planes, so accidents per mile would still be a significant statistic. Because even though planes fligh thousands of miles per trip, cars are numbered in millions, in the US alone. So I’d bet that if every car trip was one mile, which is very conservative, you’d still have more miles driven daily than flown in the US. Which makes deaths per mile a lot more scary.

      Accidents per trip would be relevant as well, but how many commercial airliners crash every day vs. how many cars crash every day? How many people die a year from commercial airline crashes vs. from car crashes? I’d bet that even per trip cars are less safe than planes.

      I live in a mostly rural area, and we have had 4 deaths on the motorway nearby over the past 3 or 4 months. And that is just in one region,with low to moderate traffic and low population density (lots of farms and woods around here). Also, never knew anyone who died in a plane crash, in over 40 years, but have had 2 close friends die in car crashes, never mind acquaintances or friends of friends. And I bet everyone, in developing or developed countries, knows someone who died in a car crash, whereas I’d bet that most people don’t have even acquaintances or friend of friends that died in plane crashes.

      So I’d really like to see numbers on that claim that, per trip, cars are safer, because in 2021, with no deaths from commercial planes in the US, that claim does not stand, because you could have an infinite number of car trips that year, and still be less safe than commercial planes with one single dead person.
