Moving at a constant speed if your in the car then there are no forces acting on you from the car. If the car accelerates then the car will push you forward and you will feel the Force of the seat pushing you. The only other force on you in a car is gravity witch always pulls straight down. Gravity is always there whether the car is accelerating or not.
There are forces acting on the car. They are just equal to the force of the car acting on the force. In example, gravity is acting on the car, but the car is pushing back equally. Therefore, the car doesn't move.
Yes, frictional forces such as air, tires against the ground, gravity pulling the car down, force of engine moving car forward. The positive force of the engine turning the drive train and the wheels is equaled by the frictional forces; so overall forces balance out.

No,because if the car is moving at a constant velocity that means the acceleration is zero. So the net force is zero and there may be some forces acting on it. Only gravity, downward.
