Earlier quoted context omitted.
The article talks about a train that can go 200mph. That makes having people drive between cities seem a rather slow option. Plus you can get work done on a train. On a car it is not possible as a driver (other than phone calls) and pretty hard as a passenger. I take your point about planes, but it's good to have more than one option and trains are good for middling distances, as there isn't all the need to check in,…
Instead of trains we're working on self driving cars. They better serve last mile and are better suited for private investment and innovation than huge infrastructure projects.
You also can't fit as many people in self driving cars, simply because having the requisite fuel storage and engine per 2-4 seater car is quite a lot of space when you can spread that around 200 people per train car. And this is before we consider that average car occupancy is something like 1.5.
