Boring Company video seems to show a Tesla Model 3 going 127 mph in a tunnel

Video from Elon Musk's Boring Company, a tunnel building company that recently was contracted to burrow under the Las Vegas Convention Center, shows the company has made some new developments in its test tunnel. As confirmed by Musk on Twitter, the tunnel now relies on Tesla's Autopilot driver assist system to propel passengers through, instead of using a carrier trolley. To demonstrate the potential effectiveness of this tunnel and Autopilot system, the video pits someone driving a Tesla Model 3 on surface streets against a Model 3 going through the tunnel.
