So the slow moving down to earth car should really be moving through a compressible fluid, rather than incompressible, right? Its the shockwave that makes it incompressible.

No, a slow moving down to earth car is moving through an incompressible fluid. The presence of a shock wave would mean that you are in compressible flow.
