hmm, another cynical way to look at it:
Tesla owners are affluent enough to have political pressure, and many are the early adopter/risk taker type. If everybody gets access to FSD Beta (city Navigate on Autopilot in Level 2 form) at once, there is more momentum to keep FSD going if there are accidents. "That's the price of progress, don't take away my FSD or I will affect your political career"
If only a small group of Beta testers have it and the NHTSA or whoever clamps down, there are less people to get mad about the sudden regulation. It's easier to take away something that people never really had than to take away a feature they are using regularly.
If people can get used to pandemic deaths, they can get used to Level 2 driver assistance systems leading to accidents. It sounds awful, really really awful, but we as a society are numb to body counts right now. September 11th level deaths happen every day from COVID, so what's a few fender benders, even a few bad crashes? I'm not saying I have that perspective personally, but it may be good timing to introduce a high risk software feature, when people's appetite for risk has increased due to pandemic fatigue.
