just use the left and right arrow keys but i put it to go up and down every 2 seconds hit the arrow key once to see full logic of it and every 10 seconds the back ground changes so it would give you 10 seconds for every 2 seconds to drive you'll see what i mean.
this gave me an idea for a kinda thing that would be like your able to drive and make a story i know its completely twisted but its just an idea.
