satisfying the safety score requirements puts you in a pool of users that Tesla can draw from WHEN they need more testers. Environmental factors means that Tesla is curating where they want more or less data. They may be looking for certain traffic patterns, driving styles, weather conditions, etc. They may also limit participation when they feel the safety risk of adding more users based on the state of the software would increase crashes, so there is a safety and PR aspect to the speed of the rollout as well.
It sucks to be stuck in safety score purgatory, but it should be pretty obvious, even with the lack of communication, why you aren't getting FSD beta yet. The lack of communication applies to existing FSD beta testers too. I'm on 10.8.1 and Tesla never informed me why I'm not on the latest version. Others are stuck on even earlier versions. This is how it's going to be regardless of whether you have the beta or not.
Elon did state during the earnings call that he wants to increase the pool of testers. Whether that comes with 10.10 or v11+ we don't know. Just have to be patient, or just try again later with SS when we have definite news.
