I have an i3 now and after my lease is up, I will absolutely either get a Model 3 or Y. There's just no other electric car comparable that will allow you to road-trip without worrying about charger access.
"Data sharing" is pretty vague but assuming you are talking about car data, it's completely decoupled from the VIN or any other identifiers that could ID you, so disabling it is just silly, but yes you can choose to not opt in.
Does "car data" include locations? There's not many people that start from area A (~500m^2 around your home) and go to area Z (~500m^2 around your office) every weekday morning, and back again every weekday evening.
And yep, this applies to anything that offers vague rudimentary location monitoring.
Correct, many folks don’t realize how much can be derived about them from even anonymous data.
Personally not interested in all this auto pilot stuff anyway. Deceleration when approaching an object and rudimentary lane assist are all I’d care for and shouldn’t require machine learning.
It does include location if you stop at a supercharger. They need to know where you were in order to charge you properly. I don't think that's one you could opt-out.
My hope is that your mobile bedroom/living room/office drives around and plugs into shared, communal kitchen/laundry/exercise/living room areas. You do your work during the transit portion and spend your free time enjoying the destinations and other people.
