The goal here is to put all of those saturday night racetracks out of business. You can’t have a race if nobody can field a car.
Sure the “modified” classes where they are built by specialty maker would sill exist, but not everyone can afford to get into that. The street stocks and pure stocks would be gone, and at most racetracks that’s half of your show and 70% of your car count.
Drag racing would be out of business.
