Elon Musk goes underground to beat future traffic

Tesla Motors founder and future-thinking entrepreneur Elon Musk has revealed plans that could see a network of high-speed underground tunnels built below cities in order to ease growing levels of congestion.

The tech tycoon, who made his millions from founding and selling PayPal, presented his vision at a TED talk recently, where he laid out plans for The Boring Company, an infrastructure and tunnelling business he set up in 2016.
