It's an interesting bar to set. And it shows how we're willing to bend that safety bar to allow seniors to drive on the roads despite their clear cognitive disadvantage.

Let's look at some raw data. Mind you, we have 100x more data for the human drivers below. ie, billions of miles vs millions for automated drivers.

Pop examined Fatal-crash rate All Level‑4 automated‑driving tests in the U.S. 1.5–1.7 per 100 M mi Drivers 70‑74 yr 1.7 per 100 M mi Drivers 75‑79 yr 2.1 per 100 M mi Drivers 80‑84 yr 4.3 per 100 M mi Drivers ≥ 85 yr 7.6 per 100 M mi

So statistically, you are much more likely to be killed by a senior citizen. So to make a consistent argument using data around safety, we should maybe be revoking the licenses of older folks?

edit: Jesus, 19% of all US fatal crashes in 2023 invloved seniors. While they make up 15% of the driver population.
