Digging tunnels less crazy than flying cars, says Elon Musk
Tesla and SpaceX CEO Elon Musk, who set up new startup 'The Boring Company' to dig tunnels to avoid traffic, said that digging tunnels is less crazy than flying cars. "It’s difficult to imagine the flying car becoming a scalable solution," Musk said. "If somebody doesn’t maintain their flying car, it could drop a hubcap and guillotine you," he added.
