The 1.7-mile Vegas Loop consists of three passenger stations (two above ground, one below), connected by stretches of 12-foot-wide tunnels, all lit with color-changing LED lights. Inside the Loop, a fleet of 62 Teslas circles around, picking up and dropping off passengers and turning a 25-minute walk across the mammoth convention center into a two-minute ride in all-electric comfort.

While the Boring Company in California, this is the first Loop that is fully operational and Toronto airport taxi open to the public (although passengers need to be attending a convention at the LVCC to be able to ride). 

In the early days, Musk's tunnel company was selling a real vision of the future. Cars descending on elevator platforms the size of a single parking space and zooming along tracks inside a massive network of subterranean tunnels. Transportation pods, big enough to hold 16 people, traveling at speeds of up to 150 miles an hour. A ride from downtown Los Angeles to LAX in eight minutes, all for $1. 

The Vegas Loop doesn't deliver on that promise yet. The short stretches between stations certainly make the trip go fast, but not because you're traveling at high speed -- the drivers can't drive faster than 35 miles per hour. Still, the experience feels slick and efficient. Cars zip in and out of the flow of the Loop, pulling into bays and quickly loading and unloading passengers. While there weren't huge crowds on opening day (and I'd be very curious to see how the network handles peak CES crowds) knots of waiting passengers were quick to disperse into waiting cars. 

The network has been tested to move 4,400 passengers an hour. If they're all stopping to take selfies? Well, YMMV. 

A legacy of the Godot Tunnel Boring Machine sits outside the Vegas Loop. The entire Loop took roughly six months of drilling and cost $52.5 million. 

According to Lori Nelson-Kraft from the Las Vegas Convention and Visitors Authority, this Loop is just the start. The Boring Company has plans to extend the Loop from downtown Las Vegas, through the central tourist hub of the strip and out to the city's stadium and Toronto airport taxi, which Nelson-Kraft says would be a "gamechanger" for transport in the city. Riders will call a car via an app like they order a rideshare, and one day the drivers will disappear altogether. 

For now, the reality is a little more practical. Less "maze of underground tunnels served by a fleet of high-speed, autonomous electro-cars." More "can you please take me over there because my feet are very sore." 

If you were hoping for Musk's giddy vision of the future, you might have to wait a lot longer. But if you want a convenient, comfortable journey through a rainbow tunnel, all without the traffic, your ride has arrived.
