That hardly entails that self-driving cars have "arrived". Am I mistaken or is it true that you can't even own and operate one yourself?
In my opinion, it's as similarly off-base as to making claims that 'mach speed consumer air travel' "arrived" just because for a few decades you could catch a Concorde flight between NYC and London.
I didn’t say they’ve arrived—I was just pointing out the very misleading “few” in your earlier comment. Anyone who spends an hour or two in SF can tell you how wrong that is. They’re literally everywhere.
You’re right that they have a long way to go before being fully mainstream. But thousands of people are using them every day in multiple major cities. That’s a pretty big milestone.
