Elon Musk is laughing all the way to the center of the Earth.。

After the idea to build tunnels hit him while stuck in traffic late last year, he went ahead and founded a business to disrupt the tunneling industry — called the Boring Company (surprisingly, the URL was available). Chatting with a。 Bloomberg。Bloomberg。

reporter, he revealed the two other names he says he considered: Tunnels R Us and American Tubes and Tunnels, or AT&T for short.。

Musk recently took the reporter on a tour of the hole and his brain — at least the parts that are thinking about building an underground network of tunnels for cars. And, like his ideas for electric cars and commercial space travel, his ambitions are huge.

Musk also wants to attack the extreme costs associated with earth-moving. He thinks the current costs — which he estimates at $1 billion per mile — are "crazy." Believing he can get the right people to figure out how to build a better tunneling machine, Musk hopes to get costs down and productivity up: In the report, he proposes boring through 1 mile of tunnel in a week (the weekly rate of his current machine is 300 feet), although he's clearly spitballing in the moment.。

Wouldn't flying cars potentially give you even more levels of traffic, without all the inconvenient and expensive tunneling?

Wouldn't flying cars potentially give you even more levels of traffic, without all the inconvenient and expensive tunneling? Yes, but Musk thinks they'll never work, especially in cities, for a simple reason: stuff falls. “If somebody doesn’t maintain their flying car, it could drop a hubcap and guillotine you,” he colorfully describes. It's a hard point to argue against.。

While the actual tunneling is slow going, you'll get whiplash looking at how fast Musk is moving. After breaking ground on a Friday in January, Musk apparently said, "Hey, what’s the biggest hole we can make by Sunday evening?"。
