I live in the bay and occasionally ride Waymo in SF and I pretty much always have a good time.

I visited NYC a few weeks ago and was instantly reminded of how much the traffic fucking sucks :) While I was there I actually thought of Waymo and how they'd have to turn up the "aggression" slider up to 11 to get anything done there. I mean, could you imagine the audacity of actually not driving into an intersection when the light is yellow and you know you're going to block the crossing traffic?

I was in a Waymo in SF last weekend riding from the Richmond district to SOMA, and the car actually surprised me by accelerating through two yellow lights. It was exactly what I would have done. So it seems the cars are able to dial up the assertiveness when appropriate.

It doesn't seem impossible technically to up the assertiveness. The issue is the tradeoffs: you up the assertiveness, and increase the number of accidents by X%. Inevitably, that will contribute to some fatal crash. Does the decision maker want to be the one trying to justify to the jury knowingly causing an expected one more fatal incident in order to improve average fleet time to destination by 25%?

Reinforcement learning is a helluva drug. I'm sure by now Waymos can time yellows in SF to within a nanosecond, whereas humans will only ever drive through so many yellows will never get that much training data.

A human can know the yellows on a few routes. A Waymo can pull over, observe a given intersection for an hour, and tell every other Waymo that exists precisely how long that light lasts.

It's not just collecting the information; it's the ability to spread it.
