A rough estimate for global life expectancy. It's actually slightly over 73, so the chances of dying in a car accident are marginally higher than I said.

The data I used wasn't related to driving frequency or age, it was purely the number of people in a random global sample of 100,000 people you would expect to die in a car accident in a given year. That of course includes people of all ages and people who never drive at all, but also taxi & HGV drivers. Even if we say people aren't in cars so much under the age of 5 or over the age of 60, that would push up the deaths per 100,000 people per year between 5 and 60 by the exact amount to keep the chance per year over a human lifetime at 17.4/100000.
