I think the GP poster was referring to the actual race, and not the peripheral parts of the event -- I don't know much about racing in general, but even with the extra "propaganda" you mention, they didn't seem disingenuous

I watch both here and there, not every race. Both Indy and F1 have very similar format with the "peripheral" parts.

OP had to have been referring to the "peripheral" parts of the race, as it's the only time celebs are trotted out.

They don't have Ja Rule calling the action during F1 races; they aren't getting Ja Rules input when there is a crash.

The celebrities are nowhere to be found during the actual F1 race.
