1) Would a random driver (random steering and throttle) also have avoided these crashes? It seems like they were fatal because several variables coincided very exactly, and really any other input would have avoided them.
2) What input is the Waymo driver using here? If these were not originally Waymo cars, then is it perceiving simulated video or getting raw access to ground truth vehicle positions?
- asdfasgasdgasdg 6y agoFor 2, Waymo has a simulation environment with a whole simulated physics and sensor suite. They use this environment to train their driving systems on far more virtual miles than the number of physical miles they drive. So presumably they induce the reconstructed initial conditions from the crash and then they run the simulation a lot of times to see if their driver also gets into the crash.

- tantalor 6y agoThey should try human drivers in a simulator. You would have to be careful not to signal when the accident was about to happen, because accidents in real life are very uncommon. You could estimate how avoidable an accident was by the percentage of human drivers in the simulated "responder" vehicle that avoided it. Maybe some accidents are easily avoided by humans because the real responder driver was distracted. I'm not impressed if Waymo driver can also avoid these. But some accidents may be very difficult to avoid for humans. If Waymo driver can perform better in these cases then it's truly remarkable.
