its harmful to the engine, but without it your car could not move as the tires would just spin. can't have one without the other although things can be done to reduce it in the engine and increase it at the tires.
Friction can be harmful or helpful when driving, no matter what time of year. For instance it is helpful when breaking and it is harmful between bearing surfaces. The loss of friction between the tyres and the road during winter can be disastrous.
metal to metal.... worn out brakes, bad oil pressure
harmful friction is when friction can do harm or be a problem for example of this is if your skiing down a hill with grass you will have to much friction then you fall and get hurt :p
Cars don't get better gas or mileage.
Friction slows down a car. As such, in order to maintain the velocity of the car, energy, i.e. gasoline, is required due to friction.If there were no friction, an impossible state, the car would require no energy to maintain its velocity once it had achieved the desired velocity.
friction can cause: 1) Physical wear and tear of moving parts. 2) degradation of materials by continuous friction. 3) wastage of 70% of energy in car engines. However, friction is useful in: 1) walking 2) car brakes, friction between brake pads and Tyre causes car to slow down. 3) techniques like friction welding.
Friction can affect a mousetrap car in several ways. Higher friction between the wheels and the surface can reduce its speed and efficiency. Properly managing friction through wheel alignment, tire type, and surface smoothness can help improve the performance of a mousetrap car.

Ways that friction are beneficial: Standing - Friction allows you to stay in position instead of moving around even when you do not want to Braking of cars - Similarly, friction makes it possible to make a car stop Ways that friction is nuisance: Wear and tear - Friction produces heat, which would flatten shoe soles, smoothing the gears or other mechanics in machineries
the front boot of the car increases the friction on the car
Friction is helpful in situations like when you are standing on a hillside. Static friction between your shoes and the surface are stopping you from slipping. Friction is not helpful in situations like when you are pulling something heavy. Some of the energy you are putting into pulling is going into heat from kinetic friction and making your job more difficult.
Friction is useful in various ways, such as enabling us to walk and grip objects. It is crucial for vehicles to move on roads and for machines to operate effectively. Friction also helps in slowing down moving objects and preventing slipping or sliding.
