It can be misleading to directly compare disengagements to actual catastrophic incidents.

The human collision numbers only count actual incidents, and even then only ones which have been reported to insurance/authorities. It doesn't include many minor incidents such as hitting a bollard, or curb rash, or bump-and-run incidents in car parks, and even vehicle-on-vehicle incidents when both parties agree to settle privately. And the number certainly excludes ALL unacceptably close near-misses. There's no good numbers for any of these, but I'd be shocked if minor incidents weren't an of magnitude more common, and near misses another order of magnitude again.

Whereas an FSD disengagement could merely represent the driver's (very reasonable) unwillingness to see if the software will avoid the incident itself. Some disengagements don't represent a safety risk at all, such as when the software is being overly cautious, e.g. at a busy crosswalk. Some disengagements for sure were to avoid a bad situation, though many of these would have been non-catastrophic (such as curbing a wheel) and not a collision which would be included in any human driver collision statistics.
