They don’t “all” have to be connected, the vast majority of available global models aren’t (IE a lot of the affordable Indian/Chinese models).

The vast majority of models sold in the USA are IE Tesla. More affordable models like the Renault Zoe afaik aren’t but I’m not sure how accessible these are in the USA. I’m not sure about the Chevvy Volt tbh… Consumers can purchase to buy a non-connected vehicle.

Out of the EVs I have I mostly use the one that is connected so I can do automations to turn on climate control etc. Connectivity is a convenience/safety thing for me and I assume others…
