Hint:
Friction formed between the tire and the road helps the car to run on the road. The friction is an advantage here.
The correct answer is: Advantage
- The friction formed between the tires of the vehicles and the roads helps them to roll over the surface.
- The round shape of the tires create a relative motion with the road that makes it easy for them to travel on the road.
- This is an advantage of friction.
