Objects like tires, shoes, and brakes work well due to friction because it provides grip and traction on surfaces. Tools such as screwdrivers and wrenches rely on friction to grip and turn objects. Writing with a pencil on paper is another example, as the friction between the pencil tip and paper allows for marks to be made.
Static friction causes a car tire to turn on the road. This friction occurs when the tire grips the road surface and prevents slipping. The friction between the tire and the road allows the car to accelerate, decelerate, and turn.
No, more friction does not necessarily mean more work. Friction is a force that resists motion, but work is defined as the product of force and displacement in the direction of the force. So, while friction can make it harder to do work in certain situations, they are not directly proportional.
Friction can affect a machine's performance by causing energy loss through heat generation. It can also lead to wear and tear on the machine's parts, reducing its efficiency and lifespan. Proper lubrication and design considerations can help minimize the negative effects of friction on a machine's work.
Friction can make it more difficult to do work because it resists the motion of objects sliding past each other. This means that when work is being done to overcome friction, some of the energy is lost as heat. The greater the friction, the more work is needed to accomplish the same task.
Automobile brakes and clutches require friction. We also need friction between the tyres and the road when we accelerate or when we brake or when we turn a corner.

No, We cannot do work on friction less surface
Rolling friction :)
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.

Friction's direction is always against the direction work is being applied to.

Friction is the force that makes it possible to stop a car - a friction between wheels and road surface is a stopping force there. Also, friction is necessary for maneuvering - if the wheels slipped, you wouldn't be able to make a turn.
