Have any of you folks given any real thought as to what brings about single file racing?
The biggest reason for single groove racing is NASCAR's attempt to "level the playing field".
The constant efforts to bring about complete parity in order to bunch up the field and nearly all of the cars being close to equal has perhaps been too successful?
At one point in time, a good mechanic could set the car up to run anywhere on the track; those were the cars that usually were found in Victory Lane. That is no longer the case.
With all the parity the field is bunched up, but no one can go anywhere if their car is no better than the car that's in front of them.
With all the cars being equal, they need to run the same line or groove around the track, they're unable to go high or low to pass and we end up with parades and expensive demolition derbys instead of racing.
But we all know that it's those lousy Goodyear tires, those boring race tracks or whatever other excuse sounds good today.
There is no way parity could have brought about a boring show for the folks, is there?
