I think it will be a good differentiation factor in a few years, that a brand comes up with an offline car, i.e. a car that you just refuel/charge and drive - no telemetry/connected features involved. It may be a niche thing in future, but certainly something that would be appealing to me as a consumer.
I think the insurance co will be the main lever in this story. If you have cameras & telemetry: standard insurance, open source offline car: pay premium.
PS: I understand we're talking about the future here, just wanted to clarify that paying a premium for less telemetry is already here and not a hypothetical case.
