> Not sure where you're getting that info. I just looked up NFPA 130 and it specifically calls for multiple types of insulation (for cables as well as concrete and steel) as well as automated water sprinkler systems, and even standp

Yes, I know that. That now means you need a way for the skates to communicate with each other and maintain a safe distance from each other before they collide and obviously slower speeds. That bare concrete tunnel is now longer bare since y

I don't quite see the purpose of illuminating the entire tunnel unless they're using their autonomous driving tech which uses a camera. If so, they've just put a single point of failure on their lighting systems.

How will the skates know that the one in front of it has broken down and need to be pushed? Especially when it's operating at 120mph?

I don't get it. How does this improve on the underground subway? I'm unconvinced that making the tunnels smaller means that the construction costs will be significantly cheaper and faster. Further, the electric skates make no sens
