How can you prove that without putting them back out on the road first? Surely, you'd agree that more is needed than just unit testing?

A driving exam also happens on the road. I'd suggest a similar, supervised test series with mandatory emergency drivers.

Closed course real world testing. I naively expect that you could test most of the listed situations in a small-medium size parking lot.
