You know nothing of significance about F1 - yet you are certain about your conspiracy theory, in between calling others conspiracy theorists.
Btw, yes it does need to be dangerous. That's one of the pillars very much understood by petrol heads past (who witnessed the genuine article) and present (who sustain themselves on nostalgia while waiting for this parody of F1 to be fixed). The danger separates the men from people like you.
You should watch the TT and let me know how, exactly, you remove the danger yet still end up with the same result. F1 is no different, except when the day-tripping, prawn cocktail brigade get attracted for the purposes of marketing to their pliable minds.
