I don't think you read the instructions of the game. You can only place cars next to another car, but if you place cars next to a car with the same color as the one you placed, you lose. So if you place a red car next to a red car, you lose, but if you place the red car next to a yellow car you get points. This is because 2 colors next to each other would be orderly and not enough chaos. Hope that clears it up :)
