Also, when I am not driving my car I park it, it is not adding to congestion. Waymo Taxis roam the streets in SF adding to congestion. I cant see how congestion can be reduced...the worst congestion happens during rush hour...replacing personal cars with a Waymo will have no effect.

Of course it is. Banning street-side parking would double or triple most cities’ navigable road space.

You can only fit 3 cars across on most side streets near me. You have more space, but does it really create better flow?

Many of these side streets and neighbourhoods are designed and modified NOT to flow, because then people would use them to get to work. Would this change that?

While I admit I see these more in the ‘burbs, this is becoming more widespread and is no longer exclusive to them.

Its been proven over and over, and there are tons of studies that show that more lanes doesnt help congestion.

Presumably they're not just roaming around aimlessly. They're also providing transportation to whoever's sitting inside.

Unless every passenger pickup is at the location of the last drop off and the timing is perfect, some portion of robotaxi driving must be empty as the taxi drives to the next pickup or at least goes somewhere to park. And I'm honestly not sure Waymos are smart enough to know where it is and isn't legal to park for some unknown period of time while waiting for the next trip, so that might not even be an option.

Contrast this with personal vehicles, which are always transporting at least one person to their destination. It seems essentially impossible that robotaxis could result in less congestion unless people share robotaxis significantly more frequently than they do personal cars or regular taxis.

Anecdotally, what I observe in SF is empty waymo cars driving around

Your parked car is adding to congestion. It takes up space that could otherwise be used by humans.

That is why parking lots make places un-walkable.

But that's not what congestion means.

Robo-taxis can pack significantly more densely into a dedicated parking space than regular cars. Snout to butt and no room side to side, as there's no need for maneuvering. A robo-taxi parking lot just becomes a dense FIFO queue.
