but we tolerated a lot more (early) death from all causes in those days, in part be cause we didn't have technology to mitigate those risks. The argument I am trying to make is that we have technology (public transit) that would mitigate those risks now, but we choose not to use it. (My assertion is that if we had a place where we had US standard driving safety requirements but more than half the miles traveled were via public transit, we would have fewer per capita injuries. Or more generally, that the per capita injuries goes up with miles driven in cars. I have so far failed to provide statistical evidence of this.)
