That seems mostly like an advert his ability in traffic, the pace compared to other is really no different (actually a few times other karts pull away from him).
What he clearly is, is consistent and decisive. The others around him make mistakes (like dropping a wheel off the track then playing with their carb) or botch overtakes allowing him to catch them and once he’s within striking distance he makes the move. He also fires someone off but thats karting. I wasn’t listening so I don’t know what he has as excuse for that.
