Yeah I also like the name, very classy (or rather upmarket) and gives a patriotic feel to it. I guess the rationale was similar to the America's Cup for example.
If you called it the Austin Race Circuit or something it would kinda feel disconnected from the rest of the US, somehow not as grand as the project is aiming to be. Looking forward to it but its such a long way off.
Oh and can the OP or a mod put the Formula 1 tag on this thread, thanks 👍
