So are you saying you want to start doing real
physics? If so, you might take a look at pyODE. 
We used it in our pyweek entry (which didn't get 
finished) and it was pretty helpful. 

Basically we just built 3d physics world for
ODE to play with and then watched that model
to figure out where to put the 2D sprites. So
when you want to move your car(s) around, you
just apply the appropriate force to the car
object(s)...

The code is here:

under cvs... see  room.py for how the room world 
is built; physics.py and roomphysics.py and 
hero.py for the collision and motion stuff... then
render.py for how to show the stuff on
the screen...
