He's right though. If they were quick enough then they'd get the top seats and the advertising, especially since it's very PC to have a woman driver right now, but no-one is. Wolff was never going to be good enough for the top level, and let's not even get started on blondie at Renault. We should also consider the fact that world in general, but particularly motorsport, is also still male-dominated in mindset.
At the lower levels yes, girls are definitely as good as boys, but the physicality required for race cars mean they'll never be on an equal footing. In terms of technique sure they might well be as good as a man, but you need the whole package. It's no different to tennis in that regard, you'd never expect a woman player to beat a man at the top levels of the game, regardless of the skill she may possess.
Will it ever change? Not in my lifetime.
