The company operates the equivalent of 25,000 autonomous cars 24 hours a day in simulation. Whenever one of them learns something new from what he's been through, he shares his discoveries with the rest of the fleet. Of course, Waymo still needs to do more driving in the real world, but the company believes that simulation testing is a necessary step before launching and deploying autonomous driving technologies. Companies that develop autonomous driving systems must eventually find creative ways to teach their technologies, as only a small number of locations allow autonomous vehicles to test their roads.
Unfortunately, the company did not share what his system learned exactly from simulation tests. But Dmitry Dolgov, Waymo's technical director, said on the stage during the event:
"The amount of driving you drive in these two functions really depends on the maturity of your system and its capabilities.If you start hard, whatever, you work on the basics so you can browse a few kilometers or tens of thousands of kilometers into the real world, but as the system evolves and your system runs 99.99% of the time, it requires very large-scale real-world simulation.
