I think the 50k miles estimate is probably pretty low given the average miles insurance companies assume most people drive per year is closer to 10k. Conservatively, that would place it closer to 200k miles by age 40.

I've always assumed the reason people don't get better at driving with that much experience is the reason people don't get much better at most of the things they do: they've never pushed themselves to the limit of their capabilities. While this can be dangerous in a car, it can be even more dangerous when you're put in an unexpected circumstance with no ability to respond calmly and correctly.
