to grip the track and give you more traction
Drag cars have large rear tires with no tread to grab more traction on the track surface. The rear tires also have lower air pressure so when the energy is transferred to the rear tires (as torque) the tires ripple and even more of the tire touches the track for more traction.
Yes, a gravel driveway typically has more friction than grass due to the texture of the gravel surface. Grass can be slippery when wet, while gravel provides a rougher surface that offers more traction for vehicles and pedestrians.

Track!
Pavement is smoother and harder than grass, providing a rougher surface for tires to grip onto, thus creating more friction. Grass has a softer and uneven surface, resulting in less traction and lower friction compared to pavement.
If you are speaking of a car with traction control, it is the car letting you know the wheels are slipping and it has entered into traction control mode.

Low Traction
Problem with the traction control system.
The only thing that comes to mind is the Traction Control.
They allow the runner to grab the track, and have better traction. This in turn allows for a better overall time.
