I'd like them, (or Indycar or Formula One) to experiment with a different format.
I don't like the fact that races are more about attrition than racing.
I don't like "the pack" where much of the field parades around at 200MPH and nobody can make a move. If anyone does, the likely result will be an accident that takes a dozen cars out.
Trying to get around lapped cars ads an unnecessary element of difficulty and danger.
I don't like races that end in caution flags.
Use qualifying to pair it down to a field of 32. Seed those 32 drivers and have a tournament consisting of 5 lap match races. No packs, just two drivers trying to pass each other to finish first so they can move on. If there's an accident, a car that's out of that race is out of the event. If the other driver caused the accident, he's DQ'd. No pit stops. No tire or fuel strategy. No caution flags. Clean up between the races. If all races are completed, there would be 155 laps, (16 five lap races followed by 8 five lap races, followed by 4 five lap races, followed by two five laps races followed by a championship five lap race): a full day's entertainment. The drivers do a lot less driving so they are safer. The cars take less ware and tear. Less pollution goes into the atmosphere.
They could do it as a preliminary to the main race., on one Saturday, one on Sunday.
I think it would be a hit.
