This reminds me of the old “bats use sonar and can fly super precisely without crashing into each other in pitch black” and then it turns out that they crash into each other all the time.

You have a source or observation for that? All I can find is the exact opposite, that they do just fine even in challenging conditions.

I often cycle a road with lots of bats hunting and one evening two slammed into my face and upper body (and one only avoided by ducking quickly). It's pretty obvious that they are not perfect navigators.

If you watch them fly it always looks more chaotic than birds.
