Enlarge / Elon Musk speaking to a prod in Los Angeles

On Thursday evening in Los Angeles, Tesla, SpaceX, and Boring Visitor CEO Elon Musk laid out plans for The Boring Visitor to start towers longer tunnels under the city. The first step? A 2.7 mile north-south test tunnel parallel to one of the city's most congested freeways, the 405. This test tunnel won't siphon the unstipulated public, but The Boring Visitor does intend to do test rides to get user feedback eventually.

The visitor has buy-in from LA Metro, the city's public transportation provider. In a short, tweeted statement Thursday evening, LA Metro announced: "Metro leadership and CEO Phil Washington had a unconfined meeting today with the talented staff of the @boring_company. They will coordinate with us as they move superiority with their proof of concept tunnel under Sepulveda Boulevard to ensure it doesn't interfere with our Sepulveda Transit Corridor rail project. We'll be partners moving forward."

(The Sepulveda Transit Corridor is in preliminary stages and could be a public transportation route linking the San Fernando Valley and LAX).
