Have you tried the Copenhagen Metro? It has a twin-bore tunnel system that allows 24/7 service with a higher frequency than the New York City Subway. It's cheap to use thanks to the efficiency of driverless trains.
What does Boring Company bring to the table? Tunnel boring machines already exist. Having cars instead of trains just increases the cost of operation.
