I'm not sure I understand what you are asking. The standard advice we
give around here for people working with vehicles is look at
"carworld":

There are several different ways you can do this. You can put all of
the cars geoms into a single space and don't check that space for
collisions. You can also set the category and collide bits and test
them in your collision callback.
