This is becoming the problem with all of his businesses - Tesla has a crazy valuation and it really seems like they're having huge trouble getting Robotaxi going in Austin given the very slow progress there.
Wamyos in SF are nearly indistinguishable from ubers/lyfts at this point. Maybe a bit slower if you don't have the highway mode enabled on your account, but they are everywhere and arrive within 5min most of the time I order one. I've ridden them so often I've lost count.
You'd have to pay me to ride in a Tesla robotaxi. That tech isn't anywhere near the same as Waymo.
