What's addressed in your comment? You didn't show any other alternative offering speeds like Hyperloop, in theory, could.
Not sure what you mean by your question about "which designs" - well, Hyperloop. Or do you expect me to hand you a finished project? It's just started. Even bullet trains took decades to get from proposal to project to finished.
Musk is a flawed dude, but the physics behind space-x aren't his weak point.
I'm not sure if you're being facetious here. There are countless examples that exhibit the contrary. Here is one as recent as a few days ago:

Below are a few (out of many others) prior examples:
“Great job team…thanks for making me trillions”

This one , as someone who often reads these types of mails is just a pep talk, to tell someone they respect me more than a rich person isn’t very flattering.
Look I think you just like Elon Musk a lot. I don’t mind him either, I just know almost all of his success is built on the back of a lot of hard working individuals, which I think is pretty hidden behind a dude in XXXL T-shirts
Can you name some engineering accomplishments that have been done "single-handedly" and thus qualify as real engineering?
You watch someone like Musk and you enjoy the spectacle and the idea of an engineering hero billionaire, or you realise that while he may have brilliant ideas and moments, I find he often fails to acknowledge the fact that he isn’t an island and even if he says things like, “I have a great team” I think it’s not enough because I’m generally one of those people who spends a LOT of time solving problems for other people within a team to help make complicated things happen…I wouldn’t have the time to go on TV half of the time which I why I likely know who is doing the real work.
I'm actually very curious on what the response to this will be.
