You, on the other hand, are overwhelmed by the challenge of maintaining vacuum in a tube that spans a mere 17 miles. At the very least, you should restrain yourself from using language like "...some idea he farted out...".
You say 'overwhelmed' but I'll just point out it is built and working, and at almost-perfect vacuum.
one day it might be, and more generally i do hope that we see more progress in the electric car world... but for now tesla only turns a profit as a car company coupled with government incentives. even then, outside of the US (and inside actually) their market share is tiny or zero with very little growth. saying that it doesn't even exist is a very good approximation to reality... if you ignore tech focused news articles and the like at least.
i wouldn't call that a success just yet... as much as we may admire the mission.
Subsidies and protective tariffs are the norm in the auto market.
It would put any car company that didn't get them at a significant disadvantage.
2) Which Hyperloop is failing? There are at least three groups, and as far as I know, they haven't even got close to testing the system, let alone know if it's a failure or not.
I'm skeptical of the whole concept, but declaring failure at this stage is no less silly than assuming it'll definitively work.
