Musk posted a video to his Instagram account that showed his underground transport system in action.
Editor’s Remarks: The man who wants to put humans on Mars, revolutionise energy consumption and connect human brains to computers is now boring tunnels to reduce traffic congestion. Musk’s video shows an electric sled blasting its way through a concrete tunnel at 125mph. The concept is to shuttle cars along a network of tunnels beneath cities to remove some of the burden from overcrowded inner-city roads. However, boring tunnels is extremely inefficient and expensive; nevertheless, Musk has significantly reduced the cost of building space rockets, so it seems the odds of this newest venture succeeding might be stacked in his favour.
