It's governed by the law of inertia, or Newton's 1st law, which says that a body will remain at rest unless it is acted on by an external force. So basically, it's the property of matter thats causes it to resist any change in motion.
When a car is moving at speed, we are moving at that speed as well, and when the car suddenly stops, we want to continue moving forward and therefore we lurch forward.
At least, that's what I think causes it

One has greater force exerting than the other. When one decreases, this disrupts the balance of the forces and hence the reactions that occur!
