That number is like 1.5 billion now and rising exponentially fast.
Also those deaths weren't all FSD they were AP.
The report says 1 FSD related (not caused by but related) death. For whatever reason the full details on that one weren't released.
Edit: There are billions of miles on AP. In 2020 it was 3 billion
Edit: Got home and I tried finding AP numbers through 2024 but haven't seen anything recent, but given 3 billion 2020, and 2 billion in 2019, and an accelerating rate of usage with increased car sales, 2023 is probably closer to 8 billion miles. I imagine we'd hear when they reach 10 billion.
So 8 billion miles, 16 AP fatalities (because that 1 FSD one isn't the same) is 1 fatality per 500,000,000 miles, or put into the terms above by per 100mil miles, 0.2 fatalities per 100 million miles or 6.75 times less than a human produces. And nearly all of these fatal accidents were from blatant misuse of the system like driving drunk (at least a few) or using their phone and playing games.
