E.g. if the system would actually only activate and transmit when let's say the airbag inflated that'd seem like a good thing in general.
Would there still be ways to exploit it, maybe but it's not the same as what was described in the article
With that said, I'm pretty sure this thing is not allowed in EU or at the very least will be too expensive to operate in Europe.
I'd expect cars to still work in remote areas or underground parking garages where there isn't any cell service, and this would simulate that.
