You catch a glimpse of a car driving down a highway. The car is maintaining a steady speed. The amount of friction acting on the car equals the amount of the car.

Although frictional forces, like the traction required to walk without slipping, could also be advantageous, they will provide a significant amount of resistance to motion. Automobile engines need about 20% of their power to beat frictional forces in moving parts. The adhesion forces between the contact zones of the surfaces, which are always microscopically uneven, appear to be the most contributor to friction between metals. The shearing of those "welded" joints and the action of the rougher surface's imperfections scrubbing against the softer surface are what cause friction.
