For Reynolds number use 2,500,000. At car speeds, and since this is air, the Reynolds number is always going to be around this for what we are interested in. dt is the time step of the movie, so keep it small. Gravity doesn't play into this simulation, so your top down view will work fine (you just wont see the effect of the air moving under and over the vehicle.
