This is how NASA writes software:
I want the software driving cars around my family to be held to the a similar standard of quality. In the context of self-driving cars, "Move fast and break things" means "Half-arse it and kill people."
Humans in the USA manage 1.16 fatalities per 100,000,000 miles travelled. Uber's software couldn't even get to 3 million miles before it killed someone.
We do this properly, or not at all.
