Hey mate....

Because of friction only we can walk and drive and vehicle.

Reason....

The force of friction is the necessary force which helps us to walk on ground. The friction is generated between the shoes and the road.we press the ground and as a reaction the ground pushes us forward.the force of friction between sole and ground provides the necessary grip which pushes us forward.
