The problem I see with the Powder puff thing is that times have changed.
Back when those events were popular, very few women drove race cars. The idea was to get a bunch of inexperienced ladies to climb into a race car for the entertainment of witnessing that inexperience displayed.

As more and more ladies entered the racing world as drivers, the entertainment value disappeared along with their inexperience. These days, it wold probably be hard to see much difference, there are a lot of very good lady drivers.

I just don't see it being a big deal these days. Sorry, Gene
