With encryption backdoors, you only need two steps, and the second step is on the honor system, which is why people resist the first step. With this, it looks like there are more than two steps, but given that all future cars will effectively support this in software and will be internet connected such that it can be enabled remotely, we really only have two steps. It only appears to be multiple steps because older cars need retrofits, but again, that is not the case for all cars, and especially is not the case for future cars. Once we are in the future, it will be clear that this first step that seems so benign is the only step where there was any difficulty and the second step can be done with ease.
That is also making a lot of assumptions that all cars will soon be mandatory internet-connected.
I expect there will be a LOT of push-back on that one, and there are still also many areas without cell coverage. Would you expect all cars would stop running without cell coverage?
Here's at least one entirely new car, with Bezos' backing, that AFAICT will have zero internet connection. [0] Considering the cost trajectory of cars, and the general distaste for surveillance, a low-cost car without those add-ons may be very popular.
And, AGAIN, the point was entirely about the GP post's massive exaggerations, not about a general implementation which I strongly oppose. You and GP evidently think it is OK to exaggerate and speak like every bad thing related to the topic has already happened; I think at least some adherence to the facts makes sense. It seems we'll have to agree to disagree. Particularly since we do seem to agree on the broader topic that general implementation of speed limiters is awful and to be avoided
