Driving through underground tunnels is likely the answer to traffic congestion in bigger cities. Just a week ago, Elon Musk said that he was approved to start tunneling a path between New York City and Washington DC, with more of a focus on the hyperloop system. However, the entrepreneur hasn’t abandoned the idea of personal cars taking this route.
Musk posted a video on Instagram showing an elevator test to lower vehicles into the system. The test car used is -- what else -- a Tesla, specifically the Model S. As they showed in a previously released teaser, the process looks pretty straightforward. Park the car on the lift, and it will sink into the Earth.
