Make car crash into pillars (moving a havok physics object with mouse controls)

One more question if you don’t mind. Why does the car pass through the blocks rather than push them around? The car is permeable, rather than a hard surface? This behavior seems different than what you see when you add a new object to the scene without explicitly moving it (like in this PG where objects don’t pass through each other)

Easier to tell here where you can move along both X and Y axis:
