Grok or not, things like your typical speeds, usage of FSD, and charging range, are being recorded and made available. Some states allow insurance companies to give a discount for high FSD use, so we know that info is being saved somewhere. I just gave away my 2000 Subaru Outback, probably the last car I've had that wasn't reporting my driving habits to someone, and even at that, my Garmin Navigator might have reported. Privacy is an obsolete concept nowadays. Just watch what you say and to whom you say it.
