A few quick questions...

I’m not quite sure which sub this belongs in, so please feel free to move it if I missed the mark 😉
🙂I’m currently working on an article and have a few questions. I would really appreciate it if you could provide verified, accurate answers—I definitely don't want to look like a total amateur, haha

1. On average, how much revenue does a single lane generate during an F1 race weekend?
2. What are the annual earnings for a venue like Indianapolis Motor Speedway?
3. Which is the shortest track currently on the F1 calendar?
4. In the US, which agency is responsible for issuing track safety permits (to certify that a circuit is safe for both drivers and spectators), and what is the typical cost for such a certification?
That’s all for now, but please, I am looking for precise data only 😉

3. Monaco, that legendary street circuit in Monte Carlo.

Most of this information isn't even common knowledge in the public eye...
Regarding the first point, modern F1 tracks aren't actually turning a profit anymore. In fact, organizers often have to shell out massive sums just to secure hosting rights from the likes of Liberty Media. Even high-quality circuits find themselves dropped from the calendar simply because they can't pull in enough lucrative sponsorship deals to stay afloat... think about places like Austin, or even legendary spots like Watkins Glen or Indianapolis.
As for Sonoma, nobody really knows the full story because the management operates under such strangely murky circumstances—something that's been picked apart extensively in publications like MotorTrend—but it serves as a decent indicator of how much track time is being utilized throughout the season:
However, you have to keep one thing in mind: the track stays busy because the rental rates are incredibly cheap. And the reason they're so cheap? It’s due to poor maintenance, both on the asphalt itself and the surrounding infrastructure. Because of those low costs, local racing clubs can easily afford to rent the whole place out for private sessions and spend the entire day driving.

In any case, I’m hardly being precise here, but that’s just how things are. 😁
