I've done just that and didn't ancounter any problems - the level was a
bunch of body-less geoms, and the vehicles interacted properly with it
(rising on platforms, get crushed between platforms - quite funny :) etc).
Of course, when creating contact joints, you have to specify one of the
bodies as "static" (zero ID).

And the static geoms shouldn't be moving too fast, or there will be
situations when it just "skips" the collision in one time step.
