As I understand it, friction is the force that accelerates cars on a road. Assuming that the car moves at a constant velocity, there is no net force on the car. But in this case, if friction acts to accelerate the car, what force acts to retard the car's motion? Surely it can't be purely the wind resistance as that would depend solely on the vehicles speed, and would not necessarily cancel out the forward fricitional force.
