Speed down the highway through heavy traffic and try to get as far as you can without bumping into other cars.

Simply tap and hold on either side of the car to steer.

Some may find it frustrating. Some may achieve incredibly high scores. But all will love it. Here's another sure thing: your iPhone will get some serious tapping!

Here's a tip: Plan your moves and choose the lane in advance. At first it may be easy to overtake other cars, but as the traffic gets heavier not choosing the right lane may not give you enough room to maneuver.
