Elon claims a lot of crazy stuff, but do you have the original source in context?

Because autopilot is not autonomous and no one claims it to be. It e.g. cannot solve crossroads or react to traffic lights.

So I guess he either said that about FSD (which would still be questionable but at least not nonsense) or he meant that drivers using autopilot assistance have in general less crashes than drivers who don't use it.

It can do all of those things though. Usually does. Usually is why you are there. I can't imagine anyone who has even just test driven one doing anything but frantically scanning the roadway while somehow white knuckling with a loose grip. The manual and the somewhat erratic behavior of the 3d model representing what it is aware of are not confidence inspiring. Added since this incident, the driver monitor camera, which uses ir illumination at night, disables autopilot if it decides you aren't looking at the road, has some false positives. The only thing I trust it for is stop and go traffic on a major highway. It does that reliably. I'm still scanning nervously to avoid a low speed collision. I've had it automatically engage brakes once in what it thought was an emergency when cruise control was off. I saw the person cutting me off and was about to brake with plenty of time. My wife agreed with the car...
