It seems to me that it's just matter of traction, in this video you are on relatively sticky Hard Racing tyres, which would not allow much sliding. So now that Sophy can't gain during the slides, since there is no benefit in sliding with sticky tyres. It's the same scenario with getting very good exits, as it can control the brake and throttle infinitely and accurately. So my hypothesis is that Sophy would smack everyone in a Rally Cross race; but, it would have a hard time winning against consistently fast driver in circuits that there aren't many slow corners and tyre options are the RS,RM, or RH.
