But wasn't the ambition to go much faster than a train? I thought this was about reaching speeds of airplanes...
If we are at speeds around or below 200 mph when the pods are full, SF - LA would still take a couple of hours. A French wheeled TGV could have done that 35 years ago. A Japanese wheeled Shinkansen could have done that even before. A Japanese or Chinese maglev version of the last 1-2 decades could easily beat that. And that's without being stuck in a dumb tube. By the time the hyperloop becomes a reality, if ever, there will be tens of thousands of miles of high speed rails around the world.
The hyperloop is a sizeable amount of current hype and a future loop with pods that barely match yesterday's high speed trains. These high speed trains, engineering wonders that actually exist, don't receive any attention in press. I'd say that the hyperloop has been remarkably good at sucking the air out of the room.
