You have it backwards. The fact that after the special condition of a crash it still allows the data to be deleted is an issue. Sure, deleting of normal data is fine, but it clearly detected a crash and did not mark the file in the special crash mode as do not delete is mind boggling. Everyone knows that in a crash detection mode that the data is very important. Not having code to ensure data retention is the laziest at best way of doing things or malevolently designed at worst. Tesla and its leadership do not deserve at best as our default choice.
