The casual racing game utilizes GPS to mirror the route of the real car, which is represented by a virtual vehicle called the "Papa Car," which in turn is chased by the player's in-game car. The player steers the car to the left or right via the phone's accelerometer, and earns points by making precise turns and picking up various objects.
Those objects are dropped by Papa Car or are associated with landmarks, such as stores, restaurants and other real-life buildings taken from the GPS map, which appear during the virtual drive as icons. The rarer the landmark, the more points can be earned. All collected landmarks are saved and are accessible via a separate page, to obtain more information about them. The points can be spent on customizing the design of the virtual car, such as changing its color or installing new parts.
All routes are saved automatically as is the current design of the car, and can be shared on Twitter. Backseat Driver comes with an online ranking where players can compete according to their total travel distance and total points. By involving the kids in the driving, the cartoon-style game seems like it could be a fun way of keeping them entertained during long journeys.
