There are no such switches on any car today. If there was my mechanics would tell me, we are a repair/body shop, so we know what systems do in cars, cuz we have to replace/fix them. Dealers do not get involved into repossessions, banks own cars not dealers, except in rare case when actually a dealer gives you loan, but they, as a rule, do not get into that
I'm strongly against such devices for cops or banks. Cops would just shut your car instead of pulling you over, (just in case you run, for officer safety), that would make your car uncontrollable, and you would crash, cops will not be responsible for damages, they have qualified immunity, even today if they chase you, they crash into an innocent motorist or a bystander and kill them, cops are not responsible. so i really don't want them to have this power, tasers proved they will abuse non lethal force, they tase people in handcuffs, on the ground, and in the back of police cars, plenty of videos exist of them doing it.
Banks also do not need to have such tool. If cops at least see your car before they shut it, banks do not, they can shut it while you stopped for gas or food, or a bathroom brake somewhere far from your home, or destination, imagine you have small kids in the cars, what are you going to do in the middle of the night, who knows where?
Not to mention such devices can and will be bypassed, and defeated no doubt, today right people know how to roll back your mileage, ( and do so in every module that your car records it) remove ecu speed limiters, block your cars communication with manufacturers servers...etc
