alt Hacker NewsI think this is one of those ideas that sounds good on paper but breaks down in practice.
One immediate problem that comes to mind is that you need a smartphone to take public transit. So if there's a teen without a smartphone, they can't take the bus, nor can someone who's phone died, etc.
One of the amazing things of the current system, as simple as it is, is that it's predictable and doesn't require coordination. You can walk to a bus stop and know that a bus will arrive and take you where you expect to go, same as the last time you've taken it and the time before that. You don't need to look up a map to see what today's route is, or to see where the stop is, or to let the bus know you're waiting for you. You just show up at the bus stop and the rest just happens in a predictable and reliable fashion.

In China, Korea and other places, a smartphone is already the required entrance ticket to public life.
It's a little bit like faulting sidewalks for assuming footwear.

I feel very strongly that if a teenager is old and responsible enough to take the bus on their own, they are old and responsible enough for a smartphone. Furthermore, it's actively harmful to send your kids out into the world without the kinds of modern tools that would make them safer and more independent.
As for "phone died," well... just find a place to recharge it. It's not particularly difficult these days and I can't actually remember the last time my phone died on me when I needed it.
OP is a really cool demonstration of what we can do when everyone carries a computer in their pocket. Uber in the US has something similar with airport shuttles. Why should we handicap new, shiny things to make them usable without a phone?
I didn't get the impression this was totally replacing static routes. Seemed to be augmenting it. But also, while your concerns are valid, I don't think they are large enough to not try these things.
In my experience, on a public bus there is reasonable chance of getting a working USB A socket. But as a private business, it's not a complete replacement of the public bus system, however apps are used by people already to book on-the-fly cheap group taxi trips in Shanghai.
For good or ill, most teens do have a smartphone on them, and even kids are often seen with smartwatches that have tracking, and probably WeChat, and every mall I've been to sells them. On the Shanghai bus and metro, people often use a Shanghai public transport card to pay, they do accept old fashioned cash though too. Powerbank rental networks are common on the street and non-returns default to purchases (~$14–$28 USD). Malls, and the Metro often has power available for free.
> you need a smartphone to take public transit
Life in China these days does not support not having a smartphone.
Renting a shared bike, using a public Wi-Fi, ordering at a restaurant, literally everything requires an SMS confirmation now. There are even automated convenience stores that require scanning a QR code to enter. App-based mobile payments (Wechat/Alipay) is pretty much the only payment method ever used. Cash and cards are almost never seen.
> if there's a teen without a smartphone
I live in Shanghai. Many if not all kids have smart watches with payment apps.

These examples are all easily solved.
I.e. replace the bus stops with terminals/kiosks which give you full service, potentially another in the middle of the bus.

In many cities, the exact opposite of that has been true in my experience. I’ve waited at bus/train stops only for it to be 20+ min late or never show up multiple times per week. The unpredictability makes it infeasible as a means of transportation to getting to work or anything time sensitive (e.g., sporting event or show downtown). This is a much bigger problem in smaller cities with rudimentary public transit, but I’ve also experienced it in larger cities like Philadelphia.
