When you contract your muscles, the car makes a turn at the left edge. When you relax your muscles, it starts going along the outer edge. Avoiding obstacles requires you to use more strength when contracting your muscles or to maintain your muscles activated for a few seconds, and collecting stars requires you to relax your muscles quickly and move the car to the other side of the road.

How much strength to use, how long to keep the muscles contracted, when to relax, or whether the relaxation is total.

This means that the brand-new car you get into to play the game may take a solid beating.
