Racing because friction slows you down but you need to go fast.

An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
there is friction in your cars brake system and without that frictiuon there your car would roll away whenever it was on a hill so this is a good example of when friction is useful.
An example of not useful friction is the friction between the tires of a car and the road surface when trying to accelerate. This friction wastes energy in the form of heat and wears down both the tires and the road, without serving a beneficial purpose in this context.
Rubber bath mats are useful with friction because they have a lot of friction and can stop you from slipping because of all the friction it produces. - thank you to this website for the answers :)

Brakes are meant to have a lot of friction and it's useful.
Most of the wind energy will eventually be dissipated by friction (converting it into heat).
Most forms of conventional movement require friction. For example, a car could not go anywhere if not for the the friction between the rubber tire and the road surface.

the friction from pushing the hull through the water is not useful as long as you're travelling.
