Why are you digging tunnels?

“Traffic is driving me nuts. Am going to build a tunnel boring machine and just start digging... We’re trying to dig a hole under L.A. And this is to create the beginning of what will hopefully be a 3-D network of tunnels to alleviate congestion. …one of the most soul-destroying things is traffic.”
