RoC was originally an event for rally and off-road drivers when it was hosted in Gran Canaria. Watching drivers like McRae, Alen and Auriol going head to head in equal equipment was a real eye opener.
My point stands with Kovalainen. He was in single seaters therefore the eventual goal was F1, which he raced in for years. He beat two very good drivers, and a multiple world champion head to head at the RoC.
As for Susie, what do you want me to say? She's there because she's a woman, and Michele Mouton runs the RoC. Other than Danica Patrick, she's about the most visible woman in motorsport. She got some podiums in Formula Renault I think if it makes you feel better.
