In car.cpp there is a point where you are adding forces.  (Better check 
the simuv3 code for that).  You could interface the driver model with 
that...

I was thinking about  shifting the bike's mass center left/right, but
I haven't found this information at the structures inside car.h (maybe
I just looked at the wrong places?)

Yeah, currently torcs does not care much what the angle of the wheels 
with respect to the road is.  However it _does_ have an effect, due to 
how the suspension is coded.  All that is missing is a way to make the 
driver shift his weight.. hm

I wont have time to build this in straight away but I'll give you some  
feedback when I get some spare time.

Thanks a lot for the patch, I've always thought it was a shame there were  
no bike models.

;)

Hello there!

A friend of mine has been developing some joysticks, and I'm always in
turn of writing its drivers and finding games to validate them. Well,
this time it was a (very) cheap moto racing joystick prototype, and
then I found the TORCS project. First of all, you have made a *great*
job! I'm certain you have already heard that before, but it's really
pretty impressive.

Since this was just a prototype for validation purposes, I didn't
spent too much time figuring out the bike physics. Instead, I just
added some hacks to have something visually convincing. Having said
that, the patch is obviously not intended for integration, but I'd
like to share it with you, just in case someone gets motivated and do
it The Right Way.

The patch itself is generated against TORCS 1.3.0. I've also made a
bike model, based on an ancient object I had lying in a corner of my
hard disk. After removing its wheels and doing some quick painting, it
was converted to the ACC format. Together with the bike there's a new
category, described in Track-Bike.xml. I've basically removed some
restrictions, such as allowing the distance between the wheels to be
near to zero (I said it was a hack! ;-) )

For those interested, here's the patch and the tarball containing the
bike and its category:
