> What part of this would a Tesla, or any other car, not be able to do?

this discussion has reached the limit of its usefulness. if you aren't able to see why having nationals in an adversary nation be in control of dangerous hardware on your soil is a big problem, nothing will aid you in understanding this.

That's not the point of disagreement. I completely see why that's a big problem. Where we disagree is the notion that Volvo isn't controlled by an adversary nation or doesn't have dangerous hardware.

If you've managed to come away from this discussion with the impression that I think it's no big deal to have adversaries in control of dangerous hardware on your soil, then I do have to agree that this discussion has reached the limit of its usefulness, because I said nothing of the kind.
