The engine does. Sometimes the wind can be behind it too

When a horse pulls a wagon, the force that causes the horse to move forward is the force of traction generated by the hooves gripping the ground. This force propels the horse and wagon forward by overcoming the friction between the hooves and the ground.
When a car is moving in the forward direction, the main forces at play are the engine force propelling the car forward, the frictional force between the tires and the road providing traction, and air resistance acting against the car's motion. These forces work together to keep the car moving in the desired direction.
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
The force that causes the car to stop by opposing its motion is friction. Friction occurs between the tires of the car and the road surface, creating a force that resists the motion of the car, ultimately bringing it to a stop.

inertia
1. force that moves a car forward is the friction force between the tires and the road (ignoring what is going on mechanically in the car) 2. if the car is travelling at constant velocity, net force is zero - forces pushing car forward are equal to forces pushing car back

when a car is speeding up how does the forward force and air resistance compare
pull
There is no such thing as "force of inertia". The passengers are thrown forward, maintaining their initial motion. This is an application of Newton's First Law, which states that an object in motion stays in motion unless acted upon a force. The force of the car brake is acted upon the car and not on the passengers. This is why the passengers continue to move forward for a second when the car stops.
forward friction on the tyres from the road..

The seat belt makes an balance forward force because when the car stops you fall forward and the seat belt makes it so the force in your body stays balanced. So it becomes an balanced forward force.
The jump is caused by G forces. The car is moving and you stop the car, but you dont stop right away. You keep going until another force acts upon you, which is yourself and gravity. This applies to the car too. First the brakes stop the wheel, then the wheel stops the axles... and so on. This causes the "jumping forward".
