* FSD Beta is a level 2 system. This means it requires constant supervision. This crystal clear to every FSD Beta driver, the car will both monitor your face, and nag you to touch the wheel every so often to make sure you're paying attention. Too many "strikes" and it will lock you out of FSD Beta for a few weeks. It's basically expected that the software will fuck up every now and then, otherwise it would be level 3/4/5 (i.e require no supervision)
* If you watch the channels that review FSD Beta (Chuck Cook, Dirty Tesla, etc), the vast majority of drives require at least one disengagement. Only very recently with recent versions you would sometimes get the mythical 0 disengagement drive. So FSD beta requiring frequent disengagements is something already well known and understood.
