What happens in the age of self driving cars?

Fewer car accident deaths, leading to more elderly people, which inevitably means a higher population of people with Alzheimers.

(Unless people highly predisposed to dying in car accidents are also highly predisposed to mudering people who will have, but don’t yet have, Alzheimers. But that seems sufficiently unlikely for the purposes of this hypothetical.)

Jokes aside, the serious answer depends on whether the link is causative or merely collerative.

At one point the amount of human induced accidents will increase since no human can account for sudden erratic brakes of a self driver, even though it predicted a correct incoming accident with another V2V connected car.
