Phantom braking is unsettling and seems like it could cause a rear ending incident but I've yet to hear of a single case where this has happened. Out of the millions of miles that Teslas have driven with automation, there should be multiple reports of accidents if this were truly a problem. Could it be that it's not as dangerous as it appears? Perhaps the car takes into account the car behind before it decides to brake and doesn't do so if the rear car is too close.
BTW: I know about the 6 car pileup last Thanksgiving in the SF Bay Bridge tunnel. A Tesla changed lanes in front of a fast moving vehicle and then slows to a stop, causing the accident. The driver blamed FSD but Teslas use AP on that bridge, not FSD, so that's not possible. Also phantom braking incidents don't stop the car, they only retard the speed temporarily then continue at full speed. The full report of this incident has not been released and the driver's report is verifiably erroneous so phantom braking may not be the issue.
