Somehow, Elon Musk keeps convincing cities to allow him to dig under them. The latest locale to give The Boring Company the rights to displace dirt directly under their feet is Nashville, Tennessee, which announced an agreement this week to allow Musk’s firm to build a 10-mile “loop” that will connect the city’s airport and convention center—an arrangement that has modestly improved traffic flow in Las Vegas while turning the city into a laughingstock of the infrastructure design community.

Elon Musk's Boring Company will build a privately funded high-speed tunnel, the Music City Loop, connecting Nashville International Airport to downtown. While state officials and the U.S. DOT secretary expressed enthusiasm, Nashville's mayor raised operational concerns and some residents voiced skepticism.
