Anytime data is recorded legal is immediately asking about retention so they don't end up empty handed in front of a judge.
Every byte that car records and how it is managed will be documented in excruciating detail by legal.
As is deleting data. Also, for, say, training data for Tesla’s software, I don’t see legal requirements for keeping it around,

At Tesla? I know about nothing about their software development practices, but from them, it wouldn’t surprise me at all if this were accidental.
Edit: one scenario to easily introduce this bug is if the “delete data after upload” feature were added after the “on a crash, upload all data you have, in case the car burns down” feature.
If you selectively delete data, courts can assume that data is the worst possible thing for a court case against you.
In my experience, they are setting automated 90 deletion policies on email so they don't end up with surprises in discovery.
Like many things, the retention policy was actually a destruction policy
