I agree with the decision too
I sympathise that a lady might now be losing one of her incomes, but just can't reconcile how parading a beautiful woman in front of a racing car is anything to do with the sport.
I can't see any reason to have them other than 'look at me, I'm young and beautiful' which (arguably) suggest the world of the wealthy is about beauty. Which then suggest a) woman are so gullible, they are drawn to wealth, and b) wealth can buy beautiful young women.
Just seems wrong to be suggesting that.
If there's another purpose for them, I'd like to know it.
