bad friction is when 2 things rub together .
not good friction in gears
There are plenty of friction occurring in a running car. Here are some examples:a) the different parts like the pistons, and the different gears and shafts in its main engine.b)The cars breaking system which uses its brake-pads and this discs breaks using friction to stop the car.c)The car moves forward or stop by means of friction between its tires and the road

Kinetic Friction replaces Static Friction when an object is in motion.
NO friction
Air resistance is a type of fluid friction (along with water resistance) and is therefore is a type of friction.
No, it will lubricate the gears. Decrease friction.

Friction is decreased.
Friction isn't always bad, but when engineers try to avoid or reduce friction, it is because of the energy lost due to friction.
Transmissions, gears, bearings, drive lines. Is there a particular thought you wanted an answer too. About the only time friction is desired, is during braking.
rough shifting of gears, slipping of gears, a burning smell from the engine may be symptoms of a bad trans axle
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
Gears are not perfect example for rolling friction. Most energy lost in gear operation is due to the surface shear stress, which is more like sliding friction. Rolling friction is due to the pressure induced torque applied on the roll axis. Under this circumstance, the equivalent pressure force doesn't point to the roll axis, which creates a torque to resist the rolling motion. A good example for rolling friction can be a running wheel of the car.
if it is an advantage then it can't be bad
