This works under the assumption that all negative environmental externalities are tracked by governing bodies in every jurisdictions, and that's simply not the case.

No, it works under the assumption that they’re tracked in literally any one jurisdiction in the world.

If it were so extremely toxic, we’d have heard about it from any of the jurisdictions where there is a racetrack, which there are thousands of around the world. Or one of the cities which already has a F1 circuit, of which there’s dozens.

It simply isn’t anywhere near the problem that GP makes it out to potentially be.

Either they're small, and the only people paying attention are a town and an insurance company, or they're so big nobody would dare (take on F1?, please).

The actual race isn't in the city. It's miles away, you can't even hear the cars while the race is on (like you can in e.g. downtown Melbourne even on the other side of the city). Nobody here in the city has a problem with it. Perhaps the residents of Montmeló where the actual circuit is do, but I don't know.

But this protest was against a demo performance this evening in the city. On a weekday night when people have to work. In a city that prides itself on sustainability and has pedestrianised many streets in recent years.

A lot of people like myself consider F1 to be nothing but a toy for big oil and billionaires with too much money to spend. It's hyper commercialised. I don't want them here either though I didn't protest. I just avoided the area. It's much harder to do if you actually live there though.

None of this has anything to do with the discussion in this thread, which is entirely about the environmental impact of the F1.

No, but I just wanted to clarify that the protests are not about that either because the races are so far away from the city. For pollution purposes they might as well be in Monaco especially because there's a mountain in between.
