Ten miles from Fresno might be too far. I just picked a distance out of thin air.
But when you have a minor stop, it's less important to build the perfect configuration. Even if you have to go outside of Fresno to get on the train, you're still in downtown SF or LA when you get off. And the traffic in Fresno is not as bad as the traffic in SF. And the flights from Fresno airport are probably not as cheap, since it's a lower-volume airport (capex per flight is larger), so you have more of a cost advantage.
So I'm pointing out a false dilemma. You don't have to choose between downtown Fresno and no Fresno. You can have a worse-is-better Fresno without sacrificing the goals of HSR for the really big cities.
