Elon Musk's Hyperloop

Elon Musk is building a tunnel boring machine that would increase tunneling speed by between 500 and 1000%. The idea is to go down, he's basically like, if we want to improve traffic, you can go up or you can go down. He has already got a test trench that's 30 feet wide, 50 feet long and 15 feet deep that runs under SpaceX.
