The miles driven are rising exponentially as the versions improve according to company filings. If the miles driven on previous versions are no longer relevant how can the NHTSA investigation of previous versions impact FSD regulation today?

Given that the performance has improved dramatically over the last 6 months, it is very reasonable to assume that the miles driven to fatality ratio also improving.

Using the value of 1.33 deaths per 100 million miles driven vs 2 deaths in 2 billion miles driven, FSD has saved approximately 24 lives so far.
