Many, Many years ago when I was young, I had a job in a TV shop. After delivering the repaired TV back to the customer, many would complain about the color (usually) or some other aspect. "It doesn't look as bright", or "The faces are a little red". Of course on many of these repairs, the color circuitry was never involved in the fault, and thus the set is performing exactly the same. The "disturbance" in their life caused them to enable "hair trigger mode" and look for things, anything, that may be amiss. Color on a TV is very subjective.
As a technician who has now been called out to their house, the only thing I found worked reliably is to lie. Go to the back of the TV and enable test mode which collapsed the picture to one thin horizontal line, then make some "adjustments" and let out a few "aha's" then take the TV out of test mode. Worked almost every time. (And I didn't have to outright lie)
I'm willing to bet if I disabled most owners' regen for a few minutes, then re-enabled it and told them that I boosted it, they would believe me.
This is sort of what Perkiset is saying; if Tesla sends a Beta to everyone, they will get all kinds of subjective responses, and very little hard logic that's actionable to a developer.
