After reading the theme of the next Release of Blenderart Magazine (car modeling), I remembered that I hadn't written a tutorial about the method that I found some months ago for automated car animation. So I have finally done it, and it is available here in PDF format, with a blend file provided.
The tutorial even includes tire compression on curves and automated steering wheel motion (including animating the characters hands with the motion!).
More from Philippe:
You 'll have only to concentrate your efforts on facial animation of your character and details, leaving the driving task to the system.
Apparently Philippe is planning on creating a system for motorcycles next. This tutorial is definitely worth a read. And he even includes a .blend file to see how its done.
