Do you think if Lewis Hamilton had been born female with exactly the same talent he would have been World Champion? I think it's highly unlikely. Somewhere along his career path he'd have encountered someone (or likely many people) that thought racing wasn't for women. Maybe his dad wouldn't have worked so hard for it, or a sponsor wouldn't have been interested, or one of the team owners along the way would have blocked him. Of course, it's still 'possible' but there's no doubt women have to work harder to get the same opportunities in motorsport. i think the point of this series is to identify talent, rather than it being a commercial venture in itself to get big crowds.
