The beta system controls for this by only allowing in people who score 98 or above in Tesla's safety surveillance program. The restrictions are tight enough that you have to actively try to be a safe driver to get anywhere close to the cutoff (some people even got pissed off because their score went down because someone brake checked them and they had to decelerate too quickly). Not everyone who buys FSD gets into the beta.

The only ethical way to roll this out at a wider scale than the scale allowed by the safety surveillance program is if it's good enough to avoid incidents like the one depicted here. I think we can all conclude that Tesla deserves the fat lawsuits if they were to green light FSD in the state it is in today.

An unfortunate fact of life, hopefully made irrelevant by the comeuppance of autonomous transportation technology (including but not limited to automobiles) that makes motor vehicle accidents a thing of the past. Until we get there, though, someone has to keep trying.
