Drag radials would also be fair because virtually every major race sanctioning body recognizes DOT legal tires as in fact street tires. Thus, fair to run in competition.

The F150th Italia (that's the new Ferrari name considering the recent Ford/Ferrari law suit) "shirley" has tires with traction approaching that of a DOT legal race/street tire. Which is precisely why the sanctioning bodies allow for any DOT legal tire to be run.

Levels the playing the field, leaving the car and driver performance as the deciding factor instead of an obvious difference based solely on tire selection. Nothing is proved one way or the other when one car has far superior traction (based solely on tires) compared to another. The results are just to lop sided to draw any conclusions.
