Fuzz Off!G 20

As you progress in the game, the police chief will steadily deploy more and more police officers to the streets in their stupid little golf carts. There's no need to make a specific effort to unlock this achievement, as sooner or later you'll need to destroy a cop car in order to get away to return a Jinjo or just get them off your back after accidentally bumping into them while returning a crate. Destroy any of these cop carts to pop the achievement.
