How about when it turns into oncoming traffic, the driver yanks the wheel, manages to get back on track, and avoids a crash? Do we know how often things like that happen? Because that's also a failure of the system, and that should affect how reliable and safe we rate these things. I expect we don't have data on that.

Also how about: it turns into oncoming traffic, but there isn't much oncoming traffic, and that traffic swerves to get out of the way, before FSD realizes what it's done and pulls back into the correct lane. We certainly don't have data on that.
