but you do feel a gravitational tug between you and the earth. Why is that?

Woot. The gravitational force is there, it is just too weak to notice. If you and the car were to drift out into space, far enough beyond any other body of significant mass, you'd start to pull together. Slowly.

The gravitational force between you and the car is too small to feel - much smaller then the force the air is putting on you for instance, and you don't feel that either!
If you and the car were 1 meter apart and your mass was 100kg, the car would have to mass 14992503748 kg for the gravity force to be equal to 1 Newton (about 1 kg).

Because gravity is a very weak force. THe mass of the car is about 1000 - 2000kg whereas the mass of the earth is around 10^24 kg. You need that kind of mass to have a reasonable amount of force exerted.
