This game is simple to explain, fun to play for all ages, adaptable to multiple skill levels and designed well -- what more could you ask.  Opening the box you'll find a set of plastic cars of varying length, a deck of 40 cards that give layouts for the cars that vary from fairly simple to dastardly.  Once you set up the miniatures as depicted, the player's task is to move the cars until a path is cleared for the target car to escape the gridlock.  The game is well designed -- it includes a tray to hold the cards and a bag for the cars when not in use; also, a card holder lets you display the current puzzle.  Very nicely done!
