Already happens Tesla has shut down several vehicles before, worse still it can only be reversed at a Tesla workshop - bad luck if that Region doesn't have any. China has a mandatory control systems. They have stoped EV's bought in Regions with significant Rebates or discounts, that were relocated into others before the rebate terms were completed.Remote access to a vehicle's electronics? Hmmmm - imagine if you bought a vehicle from a country and then your country had a "conflict" with said other country. They could then get the ****s and remotely disable every car on the road. Not a great idea IMHO.
