SpaceX and Tesla founder Elon Musk wants to get rid of Los Angeles traffic with a network of tunnels and electric sleds. In a test run video, Musk shows that his sleds can travel up to 125 MPH (201 km/h). Musk plans to dig the first tunnel between Westwood, CA and LAX and reduce the commute time from 30-45 minutes to just 5 minutes.
