Car racer: CAR AI?

Hey,

I’m making a car racer game. I have no problem with the control or anything but i have no idea how to create (a simple) car AI. So basically i want to race against AI and not other players. I found a lot of AI tutorials on youtube but those are for simple characters and not for cars.
Any idea where can i get help / where to start? (videos, books, anything else)

Thanks,
