There are some real-world scenario's where this can be used... A cut break-line will be detected by professionals, just like explosives, and every car is inspected prior to leaving with a VIP. So cutting the break line on the presidents limo probably won't get an attacker anywhere. But if the attacker could load software that stalls the engine or cuts the brakes at a predefined time (and place) the attackers can kidnap or kill the VIP without any advance indication that the car has been compromised.

Now the MMO world has it much better off, since you need a subscription to actually play the game at all.
