That’s a good point, also if you can compare like to like conditions and what the data does if you exclude teen drivers. Also if you can identify incidents related to bald tires and brake failures that wouldn’t apply.

Also would be interesting to compare human augmented driving miles to full autonomous miles. With the automated emergency braking/collision alert/lane centering assist. Anecdotally was teaching my teen to drive. Suddenly a car pulls out right in front of us, zero warning. If that happened to me, with experience on a formerly normal car, I’m pretty sure I would’ve wrecked. However my kids reflex to swerve triggered the cars “evasive steering assist” and did an action movie worthy maneuver, avoiding going off into the ditch and returning just right into the lane after getting around the other car.

Thing about autonomous driving is that it seems to get the stupid easy stuff wrong in dangerous ways, but if you have a demanding precise maneuver to make, it has a better chance once that maneuver is needed.
