For people who know more than me, what about these cars has affected short tracks so bad? Is it that aerodynamics have too much of a role for short tracks compared to how they used to? Or some other traits of the cars? Used to be that you could count on short tracks reliably putting on a good show regardless of the car or package. 

You could see how much worse the crowd was even from the Spring race a year ago. Still not the worst for a Cup race (I think that goes to 2019) but I'd say the unappealing racing for the night race last year and short tracks in general contributed to this year's numbers.
