It can make movement difficult.
It can waste vehicles energy because extra fuel is then needed to fuel the vehicle.
It can cause objects to wear away due to the friction between the two objects.
if it is an advantage then it can't be bad
A broom sweeping a floor uses friction to push dirt and debris along the ground.
Having a lot of friction can be bad when you want smooth motion between two surfaces, as it can cause heat, wear, and energy loss. In some cases, high friction can also lead to difficulties in moving objects or machinery.
It depends what you want to do with it. Friction generates heat, which can be good (if you are cold), or bad (if you are not). Friction slows down movement, which can be good (if you are about to crash into a tree with your car), or bad (if you need high performance in an engine for instance).
Misuse of friction: Excessive friction can cause overheating and wear on moving parts, leading to equipment failure. Too little friction can also be dangerous, as in the case of slip hazards. Uses of friction: Friction is essential for everyday activities like walking, driving, and gripping objects. It is also used in machinery, brakes, and clutches to control and transfer motion.
bad friction is when 2 things rub together .
Friction isn't always bad, but when engineers try to avoid or reduce friction, it is because of the energy lost due to friction.

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.

No friction is not always bad. In fact consider an example of running on wet floor. If there is too little friction it might cause you to slip and slide.

It can be bad when a gymnast is on bars because too much friction between the bars and the hands can cause calluses/skin to rip off and leave the skin raw and/or bleeding. This can make practicing on bars very painful for a gymnast.
