All these promotional ladies paid to stand around and promote F1 have lost their jobs, but the men who are paid to wear expensive clothing and watches, pose with expensive bottles of bubbles, mingle with celebrities and the rich to encourage them to part with their cash and drive around in overpriced over-engineered advertising vehicles get to keep their jobs.
The ladies were there to promote F1, just like the drivers are there to promote their teams and sponsors. This is a knee jerk reaction to #metoo and completely the wrong way to tackle the issue.
Lets ban cheer-leading, backup dancers at shows, catwalks, modelling... keep all women at home in the kitchen because you're not allowed outside if you're attractive and if you're not a female engineer you've made the wrong life decisions in a male dominated society.
Removing grid girls isn't going to change the sport, the TV director is still going to spend half the coverage showing the attractive partners and celebrities in the team garages instead of the "racing".
