There are several types of friction involved and the whole question comes down to energy and where it goes.
I will only address a few types.
The air resists the car moving through it, the faster you go the more energy it takes to push the air away then more energy is lost as speed rises because the car creates a low pressure and turbulence area behind it. Third is the air actually sliding over the body. All of this increases "friction"
Rolling resistance of the tires is cause because the tires "flex" as they roll (the bulge on the bottom when you are parked) the faster you go the more they flex the more energy they use.
All the mechanical bits in the car slide past one another, the faster they go the more energy it takes.

Why does friction increase as the speed increases?
because the forces creating the friction are rub faster(harder).
Does friction increase as speed decrease?
Relative to its surface, friction is constant (this is known as the friction constant). The speed is decreasing on an object because friction is acting on it over a period of time, not because friction is getting stronger.
Example of ways increasing friction?
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
To create friction in your hands what do you have to do?
You can increase the friction by increasing the roughness of the surface you are working on. Reduce the speed of the moving object, or increase the weight of the body you are working on. Increase the surface area of contact.
Friction increases as speed increases using the big idea of particles?
Friction occurs when two objects are in close contact. As speed increases, the two touching objects will be rubbing their particles faster against each other, causing an increase in friction.
Why does friction increase as the speed increases?
because the forces creating the friction are rub faster(harder).
What causes speed to increase or decrease?
Presence of friction, incline and so on.
Does friction cause the speed of moving objects to increase?
No, the force of friction always acts in the direction opposite to that of the motions.
Name two ways in which friction can be increased?
Okay 2 ways for the friction to increase is speed and non lubricant
What causes skateboard speed to increase or decrease?
Gravity, friction, or wind drag.

How can you reduce and increase friction?
Lubrication to reduce friction. To increase friction step on the brakes.
What increses speed?
speed is time divided by distance, so if you increase the distance then you get a moderately bigger time increasing speed and you have to think about wind, aerodynamics's, and finally friction.
How can increase friction on a moving object?
by slaiding friction increase
