I voted "maybe".
It will probably depend on how safe the system is. Certainly, if the camera driver monitoring works well enough and we don't see an increase in accidents using hands-free FSD, then I think it will be a big win. Tesla will be able to say that they have released hands-free FSD with supervision to a lot of vehicles, to a large ODD, that is safe enough. That would be huge. It would certain put Tesla way ahead of other L2 hands-free systems like Super Cruise or Blue Cruise. But if we do see an increase in accidents, I think we will see regulators come down hard on Tesla. In that scenario, it won't be a win for Tesla since the public will view Tesla as releasing a bad and unsafe hands-free FSD system. I think the condition that hands-free will only be an option for users with more than 10k FSD Beta miles is an attempt to mitigate risk by limiting hands-free to the most experienced users. And by the time, most users get to 10k miles, FSD Beta may be on a newer and safer version. So it might be fine.
It will be interesting to see how good V11 is. On the current FSD Beta, I've had a few instances where if I had not intervened, it might have caused an accident. But most of my interventions are from bad driving that was not necessarily safety critical. For example, jerky turns, waiting too long to make a turn, not moving over to the turn-only lane quick enough. The instances where I intervened and it was safety critical was when FSD Beta made a turn too tight and almost went into incoming traffic, or creeping forward into cross traffic. Overall, I would rate the current FSD Beta as below an average human driver.
Also, based on Elon's tweet about an update coming in Jan, I wonder if the hands-free option will come with the V11 release. If so, that would make the V11 release a really big deal, arguably the biggest FSD update ever. It would not just be single stack with the car finally handling all driving, highway and non-highway, with the same FSD stack but it would allow hands-free for the first time. So from a PR point of view, it could be a big win for Tesla. And it could result in an increase in FSD sales. So it could be a big win financially.
