But that would take about a billion years, with all the variations and edge cases.

  It would take the same amount of time if they're on a closed course or in a city. The difference is you'd need to pay a lot more people to work on it.

    Or you could have a large fleet of a million plus instrumented vehicles gathering data as they drive, then you could use that real world data to analyze and learn from all sorts of situations.

    Yeah, and the real world has advantages as the response of human drivers is likely more realistic. I'd bet they use this data to feed their simulators.

  They also train in simulation, where they modify real scenarios to run through variations and edge cases. [1] As of last year, they'd driven 15 billion miles in simulation - which is more than a typical person will drive in a million years. Still a ways to go to get to a billion though.

    Interesting. What is the validity of the simulations? Are they randomized? Based on actual driving events?
