Obviously I'm from the US - so my viewpoint is admittedly limited to that market (where NFL, NASCAR, and UFC rule).
The difference is important. In the US the several car championships don't have an hierarchy. The best pilots are on several series. Europeans also have different series, but ALL the best pilots are in F1
and all the young pilots in all series dream to be on F1.
Old pilots from F1 when they are aging retire on other series, being competitive on those and some, like Fitipaldi or Mansell go to the US and they still remain winners on the American series, for many years.
The best American pilots sometimes go to F1, and, with the exception of Mario Andretti, they turn out to be just average, not winners.
F1 is more about drivers than cars (and of course, they deserve the best cars). The best in the world are there. That's one of the things I meant when I was talking about F1, as a model for America's Cup (the best professional sailors).
Nonetheless, it will be interesting to see what happens with AC34 now that it is coming back to the US. .
I am not so sure about that. As you have said Americans are not interested in sailing or in the AC like the Europeans and if you don't have a large public you don't have a way of paying the event, unless a millionaire is willing to throw money away, and a lot of it.
The other aspect I was having F1 as a model for the AC is the sponsorship that is connected with payed publicity and the television rights. The F1 is a profitable business, it pays itself and gives a profit. For that you need a big audience.
That's the same with the AC and if they cannot find a large audience in the US that supports the event, than the probability is that the next AC will be in Europe, where that audience is located. I am not the one that is talking about it:
"While GGYC indicated it wants to hold the next America’s Cup in three years, the venue is up in the air, with Ellison mentioning Valencia; San Francisco and Newport, R.I., and Coutts pushing Cascais, Portugal.
“You need a lot of support from the venue,” Ellison said, adding that San Francisco has “a crowded waterfront, and we’d have to develop bases for a lot of teams.”
Bajurin and present GGYC commodore Marcus Young, who watched the races in Valencia, said that although San Francisco is a magnificent place to sail, they weren’t sure the city could match what was done at Valencia and Auckland, New Zealand, where rundown commercial fishing wharfs were transformed into sparkling America’s Cup harbors.
“Our waterfront has seen better days, and there would be a lot of regulatory hurdles” to overcome, Bajurin said, adding that the task was made more difficult because there probably will be only three years to get ready."
