Appreciate Elon Musk for this idea. But do you really want a bus sized hunk of w(ever)tf this is made out of zipping by you at 700mph?

  It's in a big, steel tube. You won't see bus-sized things going at nearly the speed of sound; you'll see a big, steel tube.

  Bus-sized chunks of metal are flying over your head every day. They're called "airliners".

    That's true.

  Lets be honest, the difference between 700mph and 80mph head across the median on is negligible. Either way you are almost certainly dead or crippled. Past a certain speed the only real difference is how large of an area your body is spread out over; dead is dead.

    of course, once it hits you it doesn't make much difference. However, the faster and/or more massive an object is, the bigger is the radius of damage that it can do, hence the more likely is for you to be affected by it. For example, a sufficiently fast and massive object can derail and hit a large building killing many, while a 80Mph SUV hitting a building wall will still, most likely, not be able to bring down the whole building.
