Actually the "immobilizer" (basically a kill-switch) is cited as one of the main reason that cars are less stolen today ... https://news.ycombinator.com/item?id=8166698

No, it's nothing like a kill-switch. It's simply a key that that actually works. It simply ensures that the key that came with your car is present for the engine to run. The truest definition of a key. There is no remote kill capability.

It's alike in the manner "stolen item does not work, reducing its stolen goods value"
