I won't say things change and get over it, but I will say that (hypothetically) when the first feature is sprint cars on a Friday and they have to pull to another show on Saturday you may not get a lot of cooperation, especially someplace where they run 5 or 6 classes and the Hornets don't finish up until the wee hours of the morning...
Maybe a compromise might be to set up some sort of a fan-accessible area along the pit fence where drivers would be required to loiter for a few minutes to sign autographs and take pictures before staging for their main.
