Answer
DISADVANTAGES OF FRICTION
Despite the fact that the friction is very important in our daily life, it also has some disadvantages like:
1. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy.
2. Due to friction we have to exert more power in machines.
3. It opposes the motion.
4. Due to friction, noise is also produced in machines.
5. Due to friction, engines of automobiles consume more fuel which is a money loss.
Answer
Here are some that you might notice:
Riding a car.
The motion of the car is brought forth because of friction. Without friction, the wheels would keep on turning and the car would remain stationary.Lifting anything.
The force of friction is what allows you to life a water bottle.
Walking. Much like the motion of a car, the ability to walk is entirely dependent on friction.
You hold objects in your hand via friction.
There are many more applications if required search internet

There are advantages and disadvantages of friction. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications to prevent slipping or sliding. But also, it can be a nuisance because it can hinder motion and cause the need for expending energy. A good compromise is necessary to get just enough friction.
Problems from friction
Friction can cause problems or be a nuisance that you try to minimize.
Makes movement difficult
Any time you want to move an object, friction can make the job more difficult. Excess friction can make it difficult to slide a box across the floor, ride a bicycle or walk through deep snow.
An automobile would not move forward very well unless its friction was not reduced. Oil is needed to lubricate the engine and allow its parts to move easily. Oil and ball bearings are also used in the wheels, so they will turn with little friction.
Wastes energy
In any type of vehicle--such as a car, boat or airplane--excess friction means that extra fuel must be used to power the vehicle. In other words, fuel or energy is being wasted because of the friction.
Fluid friction or air resistance can greatly reduce the gas mileage in an automobile. Cars are streamlined to reduce friction. But driving at highway speeds with your windows open can create enough drag on the car to greatly reduce your gas mileage.
