It doesn’t cost them much of anything to include the modem (which is the main problem), and the data they receive is very valuable. I agree that less tech is good and all new cars (not just electric) are full of stuff I would prefer they came without. But the connected Internet shit also allows for software updates OTA. That’s a double edged sword. Without it you’d have to take your vehicle to a dealer if it needed a necessary software update (for a recall for instance). But obviously, having it means they can do things to your car without you even necessarily knowing or understanding what is happening (risky, for multiple reasons, including removing features with a botched software update).
