From the Cars video game website…
Race to the finish line as you live all the fun and excitement of the next Walt Disney Pictures presentation of a Pixar Animation Studios film, “Cars.” Play as all your favorite characters as you help Lightening McQueen capture the coveted Piston Cup Championship.
* Story-based adventure that relives key moments of the movie
* Burn rubber in over 30 races and mini-games
* Explore the open-world of Radiator Springs
* Speed to the finish line with over 10 playable characters
* Make your friends eat your dust in multiplayer mode
* Features all of the major voice talent from the movie
* Cars for Wii™ emulates driver seat functionality using real-to-life driving techniques and maneuvers
Sounds like loads of fun to me especially using the controller to simulate an actual driving expierience.
