You can make money and a lot of it. But look at the dollar amount they are starting with.
I just looked at the top teams in Nascar. Hendricks is listed as 350 million

It takes a lot of money and why you see many sponsorships on those cars
In this case maybe they are trying to use big names to then pull in sponsors. Taylor Swift is super hot right now. Having her show up to events increases the marketing. A lot of cross promotion marketing wheeling and dealing going on..
how do you make a small fortune in racing??? start out with a big one...
