00:12 Chris Anderson: Elon, hey, welcome back to TED. It's great to have you here. 00:16 Elon Musk: Thanks for having me. 00:18 CA: So, in the next half hour or so, we're going to spend some time exploring your vision for what an exciting future might look like, which I guess makes the first question a little ironic: Why are you boring? 00:32 EM: Yeah. I ask myself that frequently. We're trying to dig a hole under LA, and this is to create the beginning of what will hopefully be a 3D network of tunnels to alleviate congestion. So right now, one of the most soul-destroying things is traffic. It affects people in every part of the world. It takes away so much of your life. It's horrible. It's particularly horrible in LA. 01:09 (Laughter) 01:12 CA: I think you've brought with you the first visualization that's been shown of this. Can I show this? 01:17 EM: Yeah, absolutely. So this is the first time -- Just to show what we're talking about. So a couple of key things that are important in having a 3D tunnel network. First of all, you have to be able to integrate the entrance and exit of the tunnel seamlessly into the fabric of the city. So by having an elevator, sort of a car skate, that's on an elevator, you can integrate the entrance and exits to the tunnel network just by using two parking spaces. And then the car gets on a skate. There's no speed limit here, so we're designing this to be able to operate at 200 kilometers an hour.
