Yeah I get that it's one of those things where the only way to truly test it is "in the production environment," but Tesla must understand that _everybody_ is participating in those beta tests, not just the enrolled drivers. So long as that car is near me, I'm a participant too. Bu the way, Teslas are getting more common in Israel, and though I have no idea if FSD is even available here, I've noticed that whenever I see a Tesla in the mirror, I try to get as far away as possible from it, because there's a much higher than normal chance the driver isn't paying any attention. But I digress.
The things is that, looking from the side, it doesn't really seem like Tesla is interested in any feedback, judging by their reactions to what could only be described as healthy discussions. If they're getting a lot of flak, it's because they've earned it.
