Just an observation: Did you notice that the eagle that starts the races isn't real - it's just a hallucination all the players are having at exactly the same time?
You always see the eagle right in front (and above] your car. Even when you are in the last starting position, it's still right in front of your car.
And you bet all the other players in front of you are seeing eagles of their own right in front of _their_ cars. But do you see their eagles? No. Do they see yours? No. Could it be the same eagle for everyone? No, because then it couldn't be right in front of everyone's car, right? Therefore, STK races are started by eagle hallucinations.
