Answer:
Drag, Gravity, Inertia, Friction, and Lift.
Explanation:
Drag from the wind, Gravity assuming you are driving on the Earth, Inertia from your body's wish to stand still pushing you back into the seat, Friction from the wheels on the ground and air on the car's body, and Lift from the speed and wind (even if you're not floating, you're still generating lift)
