Tech billionaire Elon Musk has reaffirmed his statement that the solution to gridlock is building tunnels beneath major cities.

The Tesla and SpaceX CEO first mentioned his idea for a new project in December last year, tweeting: "Traffic is driving me nuts. Am going to build a tunnel boring machine and start digging."
