Someone once DoS'd my car, by slashing two tires. On a downtown public street.

That sucks to have happened to you, but that sentence made me lol.

People always say this about physical tech, but the difference is ease and scalability. Slashing all the car tires in a block is harder and more traceable than sending out a small RF signal.

Remediating slashed tires is a lot more difficult than waiting for your attacker to get bored and move on.
