Elon Musk’s Las Vegas tunnel system has a trespassing problem

Elon Musk’s Las Vegas tunnel network has a trespassing problem.

The network of tunnels located underneath the Las Vegas Convention Center, built by Musk’s Boring Company, have seen at least 67 trespassing episodes since 2022, according to reports from Boring obtained by Fortune via a Freedom of Information request.

Since the beginning of 2023, 22 vehicles have tailgated the Teslas that transport passengers through the tunnel network to get into the Boring Company’s stations or tunnels.

A spokesperson for the Las Vegas Convention and Visitors Authority told Fortune that all of those incidents were “inadvertent” with drivers getting confused and assuming the entrances were “a ride-share pickup spot or entry to parking.” Only one incident resulted in a “tunnel intrusion,” they said.

Other trespassing incidents included a skateboarder who got into the tunnels via one of the passenger pickup stations.

Elon Musk started working on the Boring Company in 2016, as part of his plans to build a Hyperloop — a futuristic form of transport that aims to move people and cargo around underground tunnels at up to 700 miles per hour.

The Boring Company’s Las Vegas tunnel opened in 2021. The 1.7-mile network allows passengers to travel in Teslas through narrow tunnels underneath the Las Vegas Convention Center.

The tunneling firm wants to expand its Vegas network by building a 68-mile Vegas Loop under the city that would connect the existing tunnels to downtown Las Vegas and the city’s international airport.

However, the expansion has not been without issues. The Las Vegas monorail had to temporarily suspend operations when the Boring Company reportedly dug too close to one of its supporting pillars.

The Boring Company has also faced criticism over its safety record.

The Boring Company and Las Vegas Convention and Visitors Authority did not respond to a request for comment, sent outside normal working hours.
