Why do the nascar tracks always have dotted white lines on them?
The dotted lines in NASCAR racing tracks are there to create a feeling of speed to the driver. The lines flicking by gives the driver a continuous visual clue as to the speed, and are a good way to tell when the car is speeding up or slowing down.
So the drivers can follow them & not get lost, ha ha. (JK)
It's morris code.
They are there for the drivers, so they can keep their eyes on the track.
