Do they have a reason not to?

Noise regulations both at the governing body level and at the individual track level. Laguna Seca has the worst ones, but many tracks have them. Road America can't have night races because of deals with the local farmers.

IMSA's days at Laguna and Road America are unrestricted noise days during hot track hours. But be damned if you fire something up in the paddock outside of the daytime hours.
