not always same car give same lap time,
it depends on the driver. and the lines and how they run the corners.
so i suggest group drivers into groups base on the lap time, instead of what cars.
unexperience driver with pro tour car, run slower than good stock drivers. agree?

i just suggest for everyrace, a full ten or 12 drivers to complete, instead only 5 or 6.

it is a total different racing concept. not everyone accept.

if u run bad in one race, will be put to another cl;ass, but, practically, frequency crash will be a problem. drivers may have to change freq for each race. that is the only problem i foresee to happen.
