anyone know how these cars work?

unless it can only go forward and back, which isnt much fun at all..
they are pretty cheap too...around $14....but if it can only go 2 directions it isnt worth it cept for display haha

My guess is one button goes forward and the other goes backward and turns. Like the really old cheapy cars.
