the con argument would also include "what would happen if you deactivate a car at high speeds?" cuz I think that might cause bodily harm and/or property damage to people not involved in the pursuit if the car is deactivated while moving and it hits something.
Also deactivation meaning just engine cut-off; but still in control of steering and braking....something like a Lo-Jack......or like a governor of some sort.
But yea...I'd be in favor of it also if it meant lives could be saved from that type of nonsense.
