I am not sure how long will it take before you will not be able to buy a vehicle at all without having to consent to being monitored remotely 24x7, but it will happen sooner than later. And this coming from a developing country. Pretty sure it is much worse in the developed world.
I guess the market for second hand older vehicles might see an uptick because of this and might also see a boom in demand for expertise of maintaining and rejuvenating such vehicles.
