               After making the "Follow the Road", the challenge is now to make the car drive down the middle of the road.

               Etoys objects can "talk" to each other. If you look at the script "simpleSteering", you see that the car is turning by the wheel's heading.

               Each object has a built-in "pen" that can leave a "trail" on the "world". Pen trails can be lines, dots, or arrows.

               Etoys is a great tool to model an idea through exploration. Begin by painting a simple object.
