Assume an independent (non-Tesla) review is conducted on Tesla cars in full self driving (FSD) mode over the 2023 period, and the reviewers publish an estimate of FSD mode miles per accident. Then, by what (logarithmic) factor will this number of miles differ from the 2023 (or most recent) national average? This question resolves to the base 10 logarithm of this factor.

If no such review is conducted, this question will resolve N/A. The review must be conducted by an independent company, or government body which has access to relevant data.
