Detailed Solution

Friction is necessary to move any object. Without friction, we will not be able to drive cars on the road or even walk. When a wheel of a car is moving, the area of the wheel that is in contact with the surface locks with the surface of the road due to friction momentarily. Due to this, while rolling the other part of the wheel moves ahead. Without friction, the wheel will keep rotating at the same place instead of moving ahead. Similarly, it is impossible to walk on a frictionless surface. Therefore, we should not make our roads frictionless.
