Sasha punted himself as a F1 guru. I hate people like that. He can fuck right off (fans and all).
He's at best a very passionate F1 fan. He gets away with it because he's in SA where there are very few people connected to F1 insiders (those that are are likely not involved in media work). They are probably the staff of Ferrari, Mercedes etc.
He just throws in some technical jargon which on a surface level, can fool people in SA into thinking that he's a guru. F1 has a sizable following in SA but I wouldn't say it's fanatical to the extent that fans would listen closely to his technical arguments and bother to scrutinize as they would for cricket or rugby.
He'd have been exposed long ago if he was competing with people like Will Buxton.
I used to be a fan of his work but that started changing once he made his right-wing political views known and also praised the work of a known Apartheid apologist from my community.
