What I find missing is that the implication of this:
>The cheaper models in Tesla’s line-up have parts of their batteries disabled by the car’s software in order to limit their range. At the tap of a keyboard in Palo Alto, the firm was able to remove those restrictions and give drivers temporary access to the full power of their batteries.
has not been contemplated.
It plainly means that someone in Palo Alto can also add restrictions (possibly even stopping the car altogether) and that since everything is remote actuated possibly someone else might do the same (individually or per area, etc.).
