> do you measure by the number of toasters in use vs the number of cars in use, or by the number of hours that toasters are used vs the number of hours that cars are used?
I honestly measure the totals (as in total # of injured or killed by per year), as that gives the cost of the toast/car safety to society (which are different words for "how likely a citizen to suffer from it").
It amounts to my original question asking how many are killed (or injured) by either per year in total.
(Now for the absurd argument...) Active volcano's are far more dangerous than toasters or cars /per minute/ but since the amount of minutes I get exposed to them is so low, I tend to worry a lot more about cars. (No, I don't have any idea of how we could hack a volcano (sorry)).
