Nevertheless, people still want to know. Tesla apparently has a habit of turning of FSD less than a second before a crash happens. And, Tesla does publicly disavow responsibility. If FSD does something entirely ridiculous like suddenly veer off the road or brake unexpectedly, the driver may not have time to respond. Check out this article and lawsuit for instance:

Tesla’s advanced Autopilot driving system malfunctioned and caused one of the electric car maker’s Colorado employees to drive off the road and die in a fiery crash, a newly filed wrongful death lawsuit alleges.

The car was too mangled to be analyzed as to whether FSD was on. The surviving passenger said yes, the driver was using it. Musk denies it:

"He was not on FSD. The software had unfortunately never been downloaded. I say “unfortunately”, because the accident probably would not have happened if FSD had been engaged."
