You can execute ten vehicle takedowns while being chased by the police. Bring a pistol with enough ammo and drive at high speeds. Then, press a specific button to aim at the police car's tires and shoot them when the little hit-marker turns green. You can toggle between the tires by pressing a specific button. At fast speeds, the police car will go up in flames and flip upside down. It only counts when the police car flips. Sometimes you only need to shoot one tire, sometimes two. This does not have to all be done during one chase. You can let them kill you and refill ammo and do it again.
