In America, most people don’t live near a city center big enough to warrant an intercity train station. 75% of Moscow’s metro area lives in city limits. There is no US city like that. For DC, it’s less than 20%. Also, in America 88% of households own a car, versus 55% in Russia.

I can be at my local airport (Baltimore) in less than 30 minutes, and be seated in another 30 minutes if I’m traveling early. If I lived in real America, somewhere like Kansas City or Buffalo, it’d take like 15-20 minutes to get from parking to the airplane.
