Going to a government run gas station and having the attendant swap a battery for you is the easiest way to make this work.
Actually, that wouldn't even work in the apartment building I live in (in Berlin, Germany). Some people park their scooters in the courtyard... a public power outlet would probably be used for anything imagineable before a scooter would even get a half charge.
But "swap station", no. That's just as bad as having to get petrol. Refueling already only takes about 60 seconds, but any station that's on a commuting route will have a queue during commuting hours.
I commute by scooter. My scooter, along with our 4 other bikes, live outside, and not conveniently placed for plugging in.
As to 30 miles, I've toured Scotland and Ireland by scooter, round trips from London. But I understand your point. Most days, for most people, scooters are used for commuting single-digit mile trips. Of all the vehicles you could make electric, scooters makes some of the most sense.
When I saw the article originally, got very excited. My 8 mile commute to the office is perfect for something like this... but swapping the battery kinda kills it for me.

60 miles each direction... frequently done by quite a few people and not just as a mass event (though it looks better for YouTube).
Wouldn't want to trust a 60 mile range battery on it though.
