Some two years ago, Elon Musk decided to found a new company because traffic in Los Angeles was driving him “nuts” (that definitely sounds like him, doesn’t it?). More specifically, he founded The Boring Company to build a tunnel for high-speed transportation. Today, feeling that his vision had finally taken shape, Musk unveiled the 1.8-kilometre-long tunnel in Hawthorne, California as a proof of concept.

In the image tweeted by Musk, we see a Model X fitted with an alignment device in the front. The device consists of a deployable wheel gear on either side of the car’s front bumper and is what keeps the car from veering off course while passing through the tunnel. According to Musk, the retractable wheel gear “can be applied to any autonomous, electric vehicle, not just Tesla”. “If driver passes out or goes crazy those tracking wheels ensure the car stays on track,” he added in a statement.
