You can already DoS people from opening their car by using a jammer, or expoxying the locking mechanism.

Lol, true that. I prefer all of:

- superglue and baking soda in the lock tumblers

- 10 lbs / 4.5 kg of sugar in the gas tank

- pulling the fuel pump relays and spark plug wires

- unhooking the starter positive solenoid wire

- slashing the tires' sidewalls so they can't be repaired.

DoS complete. :) Maybe a swift kick in the bumper to set off the alarm at that point. ;)
