> “Since introducing this hardware 18 months ago we’ve accrued 780 million miles,” said Anderson. “We can use all of that data on our servers to look for how people are using our cars and how we can improve things.” Every 10 hours Tesla gets another million miles worth of data, he said. For those following the space, this is an amusing quote, because a RAND study recently came out pointing that given known human accident rates, to have a statistically significant improvement in safety would require data from - gasp - hundreds of millions of miles of self-driving car travel, and with an expensive testing fleet of as many as 100 cars, why, that would take decades! Not that the calculations were wrong, but I think everyone kinda laughed at it, and this quote emphasizes why. Anyway, this is the sort of method you would expect. Everyone who can records car telemetry and does training/evaluation on simulations using that data. The only surprising thing here, I guess, is that Tesla is doing evaluation live rather than recording everything and pushing to Tesla servers and running the simulations there.
