No, specifically not those. Subways are great for moving masses of people in a city, but they have long lead times in building and require some amount of density. I rather liked living in London, but say I wanted to go from my flat by China Wharf to play some footy at Burgess Park? 10 min on a bicycle, except I'd lose my bicycle. So 10 min on this scooter thing, or it's half an hour by bus or walk.

Or say I wanted to go down to my office in Levallois-Perret from where I'm staying in Gennevilliers. 20 min by bicycle / scooter. 40 min by metro / bus.

There are a diversity of destinations and rail is great, but it's no substitute for micro-mobility. And that's in London/Paris where trains are every few minutes down to every minute. In America? Subway is not competitive for these distances.

NYC spent $2.4 billion to extend one subway line 1.5 miles. I’m only jokingly suggesting this, but that’s enough to buy about 5 million electric scooters in a city of 8.5 million people.

If you persuade the NIMBYs that is.
