I think you might misunderstand the statistic. He's saying one out of every 70 deaths. If there were only 70 deaths a year, one would be from a car accident. Far more would be from
suicide, cancer, and heart disease.
I grasp that. ~1.5% of deaths is a significant number. People worry about getting brain cancer or being struck by lightning more than they worry about the risk of being annihilated by a machine, despite the latter being more common.
