A bar chart titled "Deaths from Wars & Cars" the Leftmost bar is WW2 at 78M, followed by Cars 72M, Mongols 39M, Taiping 25M, Ming Qing 25M, 2nd CN-JP 20M, and finally WW1 19M. A note at the bottom states "Showing estimate midpoints"
Ok, then since 1914 cars have killed more people than WWI, that's the same time frame. We don't look at deaths from WWI that way though because we view it as a discrete event that took place between 1914 and 1918 and look at that event. No one compares wars by deaths per year, it's deaths per war. We look at how many people were killed because of this thing, be that war, disease or technologies, that is the human cost of that thing.
If you look at the cost of things that were paid monetarily you don't look at the cost per year, at least not after the fact. If your comparing the cost of your house that you paid $10,000 a year totalling to $200,000 to a car you bought all at once for $10,000 you don't say they cost the same or they can't be compared, the house cost more.
