My concerns are the computerization of vehicles in general. The issue is not entirely with the telemetry itself, as you frame it. My issue is "what happens when the telemetry is not available?" You, and perhaps your friend, seem to be framing the problem as though the concern is that the car is filled with "spyware." My issue is that the car is filled with "DRM" from the manufacturer. When I buy a car, I expect to own that car entirely, forever. If I wanted to rent the right to someone else's car... I'd lease a car.

Musk touts the CyberTruck as "the perfect armageddon vehicle" but if you have no cell phone service how do you charge the truck? What if Tesla disappears, or GCP is down, or WW3 actually happens and the datacenters go dark? Can you operate the vehicle? What if the power goes out because... Armageddon. How do you fuel the vehicle?

What if Musk sees what I said about him on social media and accuses me of violating the TOS? Will he disable my vehicle remotely? I've seen this in the real world when a machine shop missed it's payment to Haas.

In a real armageddon, my 1997 shitbox would still function. My 2013 F150 would function right up until the EMP hit. A 2025 EV probably would not make it to a fueling source within 24 hours after the power goes out.
