Fatalities per mile is a tricky metric for comparing across modes, though. At least in the US, people getting cars often comes with adopting a car-centric lifestyle: you move to the suburbs, your commute and trips to the grocery store get significantly longer, etc. This is why fatalities per mile are higher on a bike, but fatalities per trip are actually slightly lower than a car: people with cars take longer trips.

Maybe I'm just dense but how does that invalidate parent's point? Based on what you are saying (difference in trip length), it appears that fatalities per mile actually does a better job (than fatalities per trip) at representing the relative safety of different classes of vehicles...
- lmm 9y agoThe question most people care about is something like "would buying a car make me more or less likely to die". If buying a car means you're safer per-mile but leads you to take longer trips, then not buying a car is safer.
