Yeah but I don’t want to travel on a train packed with randoms, some of whom are unpleasant or dangerous.
Have you taken public transit? Either it is good or it is awful.
The only country whose public transit was actually good is Japan, and why is deeper than just having a good transit system.
The privacy convenience and comfort are why I prefer Waymo over a bus/rail or even uber.
I will pay for an air taxi if it’s a good service.
