The Safety Score references are obsolete, there are no requirements to get FSD Beta other than having FSD and the appropriate hardware. Once you request the Beta, it usually doesn’t take more than a few days to get it.
However, it also depends on which software is currently installed in your car. What do you have? The latest FSD Beta is 2022.40.30.10. If you have a newer build installed, you won’t get the Beta until it becomes available in a newer build than the one you have.
