The car only has one race which is already pre-paid. The rest are not even close to being planned or decided on yet. The entire first part of the post is about that.
I don't believe any conference will ever agree to put up their sponsorship decks publicly. I will absolutely ask them, but so far it's been a no. They will always refuse to disclose because they want to charge sponsors different amounts and hide which speaker paid what. We demand that we are treated the same as our competitors - Polkadot, Solana, and other long-term chains. Attending conferences in general isn't fun for anyone, it's very long hours of work and it's unpaid.
