About navigating space, I have no comment, but about driving a car safely: My non-blind and somewhat functional 90-year old uncle can sit in a car and drive it

About navigating space, I have no comment, but about driving a car safely: My non-blind and somewhat functional 90-year old uncle can sit in a car and drive it quite legally at the moment. I'm pretty sure self-driving cars are less dangerous on the roads than he is, but we're not willing to test that assumption.
