The strong argument is that a car can't stop immediately, and we humans are always predicting and anticipating what may happen next and taking precautionary action. For example, if you are driving along and see kids playing in a yard with a ball, and that ball is thrown heading for the street, and some kid is in the lawn looking up running directly for the street, you would know to expect that kid to run right between parked cars and be in the street, and you would slow down. Our AV friend would kill him.

We humans are constantly predicting what might happen next based on patterns of events by systems we understand the causality of without realizing it - it is a basic survival skill that current AV's entirely lack.

Some situations are much better with intelligence, but I don't think your example is very convincing of your point either. If the kid is running toward the street then a momentum calculation is plenty.

The point is the kid is seen running on the yard as you apprach, however there are parked cars obscuring the view such that there is no way to know the kid will continue when no longer seen between the cars and into the street without anticipating that that might happen. Momentum is not helpful the moment the kid is not in direct view.

Why do you think so many animals, with such great perception, end up road kill? The point is, perception does not a safe driver make!

> Momentum is not helpful the moment the kid is not in direct view.

Assuming things still exist for one or two seconds after losing sight of them isn't a difficult task. It's still a pretty basic momentum calculation. It's not about modeling the mind of the child to know if they'll continue: the dumbest option says motion will continue and gives you the safe result here.

> Why do you think so many animals, with such great perception, end up road kill?

Because they're not cautious around cars and/or wait for the last second on purpose? Switching to the perception of the thing getting hit is a very different context.

Well, we can see what actually happens in the near future, assuming any Waymo's drive around SF without a driver - so far all the many I've seen have a driver.

They've had a lot of driverless Phoenix service, I think.
