Elon Musk’s Boring Co. tunnel design critiqued by MIT tunneling expert

The tunnel designs of The Boring Company were recently critiqued by a tunneling expert from the Massachusetts Institute of Technology.

In a statement to Forbes, tunneling expert and MIT engineering professor Herbert Einstein stated that The Boring Co.’s concept is easier said than done. Einstein noted that apart from being smaller than the industry standard, the Boring Company’s tunnel design appears rather conventional.

“His machines that build tunnels look pretty standard. I’ve not seen anything from him that is different from what other people do except for the smaller diameter. What is new, or somewhat new, is that pod, the thing that goes into it and goes over long distances. This really looks like more a vehicle development, rather than tunnel development,” he said.

Einstein stated that the Boring Company’s decision to reduce the diameter of its tunnels to just around 14 feet in diameter would genuinely cut the startup’s digging costs. He did, however, state that geological factors such as methane pockets and tar deposits have to be taken into consideration when the company actually starts boring underground.

The tunneling expert further noted that small tunnels have already been attempted in London during the 19th century, but they were eventually abandoned in favor of larger subway tunnels due to safety concerns.

“Originally the subway cars fit into these things snugly. They don’t do this anymore for safety reasons. You want to be able to evacuate a train when it gets stuck, and quite literally, if the wall is next to the train, you cannot do that,” Einstein said.

Constantine Samaras, an assistant professor of civil and environmental engineering at Carnegie Mellon University, also expressed his doubts about the Boring Company’s tunnel design in a statement to Forbes. According to Samaras, Elon Musk’s tunneling company would likely face engineering challenges due to the technology involved in the projects, such as the elevators that will be used to lower cars and transport pods into the tunnel systems.

“The concept of car elevators on skates add a bunch of engineering challenges, such as reliability and safety of the elevator, loading and unloading times, and the number of dedicated areas in a city you’d need to do this at scale,” Samaras said.

The Boring Company has taken notable strides during the past few months. Despite being only being a year old, the Boring Co. has proven its tenacity by becoming one of two final bidders for the high-profile downtown Chicago-O’Hare transport system, beating out two other competitors. Its plan to build a 2.7-mile proof-of-concept tunnel in Los Angeles, CA, has also been granted an exemption from environmental review by the City Council Public Works Committee. In a recent SEC filing, it was also revealed that The Boring Company had raised $113 million worth of funding, with $100 million of the amount coming from Elon Musk.

Tesla CEO Elon Musk has confirmed that the company will roll out a new feature for in-car Grok as it is rolling out to vehicles for the first time.

Grok was just recently added as a feature to Tesla vehicles within the past week, but owners are already requesting some small changes to make it more convenient to use.

Tesla debuts hands-free Grok AI with update 2025.26: What you need to know

The first is already on the way, Musk confirmed, as WholeMarsBlog requested a simple, but useful feature for Grok as it is used within Tesla vehicles.

Whole Mars requested that “Hey Grok” be used as a wake word, automatically activating the AI assistant without having to touch any buttons. Musk confirmed it is already in development and on the way to vehicles:

This feature is incredibly similar to that of “Hey Siri” with iPhones and other iOS devices. The phone will recognize your voice and hear that prompt, automatically activating Siri. Apple’s assistant will then perform whatever task it is asked to perform. It’s a simple but effective performance feature.

Grok is already getting its first reviews from owners as it rolls out to owners for the first time. It is a long time coming, too. Tesla has been hinting that Grok would be enabled in the vehicles for a while now, and it just started its initial rollout last week.

Grok is available in vehicles with the AMD chip and requires Premium Connectivity or a WiFi connection to use.

Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think

Tesla has finally released one key detail about the Supercharger Diner, and it is bigger than what it appears at face-value.

Tesla has revealed a key detail of its Supercharger Diner as its launch date appears to be nearing, based on what we are seeing at the site currently.

The Supercharger Diner is located on Santa Monica Boulevard in Los Angeles and was first proposed as an idea by CEO Elon Musk back in 2018. Musk envisioned a drive-in movie-style 1950s-inspired diner that would feature elements such as servers on roller skates, large movie screens, and a menu inspired by classic treats from several decades ago.

A project that first broke ground in 2023, the Supercharger Diner has been in development for over two years, as Tesla performed demolition work at the site back in February of that year.

It has slowly moved forward, and drone footage shot this week seems to show things are nearly up and running. Musk even mentioned that he had eaten at the Diner Supercharger this week.

There are still details that Tesla has yet to announce and confirm. The most important thing is regarding the menu that will be served at the diner.

Tesla has not hinted at what it will be making for patrons at the restaurant, but Musk commended the food and said the diner would be one of the coolest spots in LA.

However, we now have details on another important thing about the restaurant: the hours.

Images taken by Aaron Cash of ABetterTheater.com show the diner will be open 24/7, as it appears on the front doors of the diner:

At first thought, it seems this will operate like any other diner, as many are open for 24 hours a day. Diners typically serve large menus with numerous options, catering to the tastes and moods of anyone who walks in.

People of all walks of life eat at diners, as the food is typically affordable, tasty, and available at any hour to serve those who are night owls or those who work non-typical schedules.

However, Tesla is a bit different, and it seems that this new venture into food service could eventually transition from human servers and cooks to robots, most notably the company’s in-house project of Optimus.

It is something straight out of a Star Wars movie. I can think of Obi-Wan Kenobi visiting Dex in his diner in Attack of the Clones to figure out where a poison dart was sourced from:

Eventually, Optimus will likely be working as an employee in the Tesla Diner, and 24/7 operation will be performed by the humanoid robot that aims to eliminate trivial tasks from humans.
