Just as with wealth the average is drastically skewed by outliers. I don't recall precise numbers off the top of my head but there are plenty of people who have commuted daily for multiple decades and have never been in a collision. I myself have only ever hit inanimate objects at low speeds (the irony) and have never come anywhere near totaling a vehicle; my seatbelts and airbags have yet to actually do anything. Freight drivers regularly achieve absurd mileage figures without any notable incidents.

As I stated earlier I agree with the broader point you were trying to make. I like what they're doing. It's just important to be clear about what human skill actually looks like in this case - a multimodal distribution that's highly biased by category.
