Friction is useful when I want to stand up (trying to stand on a frictionless surface is difficult, and dangerous), but more friction is a problem when I am ice skating. Friction with my car tires is useful when I am driving on a road (especially if I want to stay on the road around a curve, or want to speed up or slow down), but more friction on the moving parts of the engine is a problem.
