Though friction is said to be a waste of energy in most of the times, it is really useful at many times in regular life.
We need to increase the frictional force while pressing the brakes of a car or a bicycle to stop it at the right time.
The friction on the brakes also helps the vehicle to slow down whenever required, to avoid accidents.
The friction on the soles of our shoes need to be increased to have better grip on the ground while walking, which helps us to keep balance.
