I dislike that statement, too, but for different reasons.

The 30,000x larger sample in the aggregate means the calculated fire rate for non-Tesla cars is probably a more reliable number. Maybe those 100M Tesla miles were "lucky"? Possibly not, though - I don't know enough about cars to guess.

The 3 trillion aggregate miles includes a lot broader sample size of car age than those from a single company that's 10 years old. This, to me, seems important to control for.

Finally - I bet the usage profile of a Tesla is different from the median usage profile of every random car on the street and throughout the country.
