Hot wiring is a method used to start a vehicle without a key. This technique involves connecting the ignition wires directly to bypass the ignition system. It is often associated with car theft, as it allows unauthorized individuals to start a car without the owner's consent. While hot wiring can be seen in movies and TV shows, it is not a common practice for modern vehicles. Most contemporary cars have advanced security systems that make hot wiring difficult or impossible. Additionally, tampering with a vehicle's ignition system is illegal and can lead to serious consequences.
