WAY LESS killed by drunk drivers over the course of history though. Thank the vaccines that have reduced the measles incidence here and the other scientific progress that has improved the prognosis of what cases still occur. And apply that science to reduce the incidence of drunk drivers and improve the chances of the remaining victims. I've been hit by a drunk driver and would have been killed absent advances in auto science over the prior century. Parallel advances in medical science kept me from ever having measles, a disease that would have been inevitable a century before.
You mean the vaccine MMR, in which I still got measles 8 months later?
Cats are much younger than measles, so yeah, cars would look safe being only a little over 100 years old. However, when you fairly compare the time periods of say, the last decade, or even just the 1950s or 1960s, cars were more deadly than measles during any of those time periods. We could talk about the 12th century if you like, but we ended that century. Long time ago.
