Indy may not be the ideal F1 track - however it's facilities are top notch, and certainly worthy of hosting a F1 race.
I don't think there's anyone that knocks Indy's F1 facilities, it is top notch. Bernie's biggest complaint about Indy (other than mucho $$$$$$$$$$$$$$$$$$$) is that the city itself has no "night life", whatever that is (I've never been to Indy for any race, let alone an F1 event). For Bernie, if it ain't uber-luxorious to kiss mucho ass, he's not happy with it. Another knock against Indy is the complex known to many fans as "Mickey and Mouse" (Turns 9 and 10, the double hairpin turns). Indy did redo that portion of the circuit for MotoGP, so maybe F1 cars would work on that configuration.
Indy is a dream for any race promoter, as where else in the world can one have a race and have nearly two hundred thousand asses in the seats? Very, very few, I imagine. Indy also has history (I think it's the second oldest operating speedway in the US, second to the Milwaukee Mile). The people that live in Indy (or Speedway, IN for that manner) are most likely passionate race fans, so you have a large core built in there.
Here's some interesting news that might keep Sauber out of F1:
The specialist publications Blick and Auto Motor und Sport report that, in order to avoid a $150m fine for not honouring the Concorde Agreement, Toyota is instead looking to hand over its team entry to Serbian outfit Stefan Grand Prix.
Monday or Tuesday's FIA entry list, however, will reportedly precede detailed talks about the coveted thirteenth and final 2010 team spot.
Stefan GP, headed by the engineering company AMCO and its chief executive Zoran Stefanovic, filed a complaint with the European Commission in August about the FIA's team selection process.
It is reported that the team could use Toyota engines at a price of 5 million euros in 2010 and 2011, as well as the Japanese marque's Cologne facilities until a move thereafter to Serbia.
It's entirely possible that even if Toyota sells to this Stefan GP, Sauber may still appear on the grid after their investor group, Qadbak, dropped out. Problems surrounding Qadbak had led to team principles not wanting to add Sauber as a 14th entry, but with it out, Sauber may still race if Toyota sells to avoid a fine for not honoring the Concorde Agreement.
Sometime in December is when the FIA will deal with the 13th entry. Until then, we'll just have to enjoy F1 politics .
