Elon Musk's Plan For Tunnels Beneath Los Angeles

According to Business Insider, Elon Musk discussed his plan for hundreds of layers of tunnels in LA to ease traffic congestion.
On a Recode podcast published Friday, Musk bemoaned the tremendous costs to bore tunnels currently.
If the construction can be made cheaper, Musk said, he could bore hundreds of layers of tunnels.
“We do expect to, over time, create a network of tunnels under greater L.A. and I think this is really the key to getting around the city very fast.
