Just tossing off Bihop Gresta and Hyperloop Technologies as a " non existent truck " is a bit arrogant.
I mean, I know we're all jaded here, and with good reason, but HTT does seem to be a going concern.
If you follow the links from Gresta on Wikepedia, to Hyperloop to Linkenin on Bihop Gresta and more all kinds of interesting parallels appear, including those of locations in India, Dubai and even Chicago ,Illinois.
I'm not saying any of this is necessarily relevant, but who knows ?
Your comment about "non- existent trucks" brings to mind comments that must haved been made about Steve Jobs and Apple Computers in the early days.
We are all hoping we're in at the start of something big.
