"has the capability" key phrase you completely missed.
You are completely missing the point of the article and the iphone feature. I HAVE the capability to use ApplePay and ride anywhere in major cities NOW, just like millions of other riders each year. THAT is the point of this feature being released now. and it's a GREAT feature. Personally, I serve as a very useful example of how great this is. My daughter lives in NYC, I do not. She uses this feature daily. When I come visit and we explore the city, I don't need to buy subway tickets or get some sort of transit pass. I pull out my phone. Done. It's very rare that she and I take an uber in town. It's just not worth it.
There MIGHT be an option, perhaps maybe someday in our lifetimes, to ride a Boring tunnel somewhere useful. Maybe. There MIGHT be an opportunity to ride an AI-powered car in the next few years to somewhere useful. Maybe. But skipping the overall cost to infrastructure and society of one over another, are thousands and thousands of people a day in a big city going to spend 3x, 5x, 10x or more to get to their city destination more slowly when you can ride the subway for a couple of bucks and get to the same place faster?
Last time I was in NYC I had to get from Harlem to Brooklyn, with a coworker, on a rainy day. He and i traveled to our destination at different times. I took the subway and, for $3 I was there in something like 40 minutes. He took an Uber and it took him over 2 hours and cost him well over $100.
I fail to understand how the Boring Company does anything beyond digging a tunnel for cars to go through. New York has tunnels. They carry cars (and trains). Why is the Boring company even part of the argument here?
For Boring and Waymo, my suggestion is to look at places like Pittsburgh, as many autonomous driving companies have done. small-to-midsize city, with very complex roads. A subway that only goes south from downtown. No subways north, east, or west. Mass transit is buses, and they are not looked upon favorably by the car-owning sect. The surrounding city and close suburbs are ripe for improvements to mass transit, but the city doesn't have "big" money for infrastructure projects like that, and building subways to the unserved areas would cost massive amounts of money given the hilly geography. Get the boring company to make a tunnel from Pittsburgh to any distance north of the city then report back to us.
