That is possible. I also think that we could see more delays in FSD Beta going out at all, even to the people with scores of 100. After all, developing FSD beta is difficult. There are lots of edge cases, possible regressions, etc... The dev team could tell Elon that 10.2 is not good enough for wider deployment. Maybe 10.3 won't be good enough for wider deployment.
Yeah, I think the 1000 people per day is suspicious too. it seems like a big number. If they continued at that rate, they would probably deploy FSD Beta to every FSD owner in just a few months. That's not early access, that's wide public deployment.
if they do 1000/day, it could just be until they hit their cap. So if they set a cap to say 10,000 people in Early Access, then they could deploy FSD Beta starting with people with scores of 100 and going down, for 10 days. And then stop deploying.
Maybe I am just feeling pessimistic but I feel like it might be awhile before we actually see FSD Beta.
