This was testing by an independent group that generated their own metrics which were heavily slanted toward driver monitoring rather than automated driving.
It also used out of date Tesla firmware. The specific test in figure 3b of the article used to ‘trick’ a Tesla hasn’t worked for months.

FSD still is a way to go before it gets released out of beta.
