Though technically a glitch, the classic car launcher trick is so prevalent in open-world games (see swing catapult in GTA IV, and gate launcher in GTA V) that you wonder whether the devs include it on purpose. Want to do this yourself? Here's how: Blow up a car and push it up against a wall (ideally blow it up against a wall). Get into another car, and use it to push against the wrecked car on the wall. Enjoy the ride
