Elon Musk replies under a Tweet on the Boring Company and 55 Vegas Resorts. When asked about using Tesla FSD in the tunnels, he replied, “Maybe later this year”. It is likely that the Boring Company is working on making it happen.

It is known that the Boring Company underground loops are working with manual drivers currently. These loops and controlled and have tunnels with clear lanes. Having Tesla autopilot in such transportation could advance tunneling technologies. This is not something that is just revealed, it was already known that the Boring Company will be adding a Tesla fleet with no driver.

Currently, the Tesla FSD updates are showing progress. Where update like 10.12.2 is known to have been received well by the software testers. The confidence in the driver assist is increasing and the FSD Beta interactions could be ready with some more advancements. In addition to this, Tesla not being able to provide the Full Self Driving technology completely despite many promises, relaunches the enhanced autopilot option at $6,000. Testing in the tunnels could also mean more data for Tesla.
Testing the technologies
But there are certain risks attached to it as well. As they are closed loops if the car were to stop without prior notice, that could put a stop to other Tesla vehicles going in the same path. Most recently GM’s Cruise stopped working without any reason in San Francisco, causing road traffic for hours. These were driverless vehicles, and such defects are generally found when tested out in real-life examples.
Zip around Vegas super fast with Teslas in tunnels!

Las Vegas is pretty much becoming the city where The Boring Company’s tunneling technologies are being put to the test. Just recently, the tunneling startup opened its Reports World stop, the first outside the Las Vegas Convention Center. Assuming that The Boring Company’s tunnels are extended as planned, the completed Vegas Loop would have an impressive 55 stations.
Initial reports from Las Vegas indicate that the Resorts World leg of the Vegas Loop seems to be at a soft opening of sorts, though visitors who wish to try out the tunnels could pay $1.50 for a single ride. A Day Pass is also available.
Musk’s update hints at Tesla’s increasing confidence in its advanced driver-assist system. It does make sense, seeing as the last few FSD Beta iterations, such as v 10.12.2, have been received well by the company’s pool of testers. Tesla has been refining FSD Beta since the program launched in late 2020, so there’s a good chance that the system, even in its current state, is already proficient and safe enough to navigate well-lit and well-marked tunnels.
