> It's that, at every step along the way, there were a group of people who doubted that cars could do that thing

...Can you cite that?

> And then the thing we said they can't do changed to something else.

...And they were the same people?

> We are undeniably continuing to make progress

Where did anyone deny this?

> To suggest things are slowing down

Where did anyone make this argument?

The quote from TFA:

> but the hype has promised completely autonomous cars reliably zipping about in rush hour traffic.

The author did not restrict that to SF, and is presumably referring to "hype" that "promised" this globally.

You conveniently left out the first part of the sentence you quoted:

> Currently available software may very well make human drivers both more comfortable and safe...

Which is objectively not what Waymo does, and whether intentional or not, invalidates the progress that has been made.

Also, immediately preceding that:

> Driverless vehicles in closed systems have been in use for a long time.

Which is also not what current frontier self driving technology is.

> Where did anyone make this argument?

The title of the article is quite literally "Is Winter Coming?"
