Tesla owner scores Elon Musk’s “V1” Boring Brick to perform drop test comparison
A Tesla owner recently acquired a rare “V1” sample of Elon Musk’s Boring Company brick for a durability test. Dan Markham from YouTube’s What’s Inside channel was able to get his hands on two Boring bricks and had some fun performing a drop test to compare its durability with potential competitors in the market.
Markham managed to get a hold of two Boring Bricks from the first batch of 500 “V1” pieces, thanks to a Boring Co. employee. The Tesla and SpaceX CEO has talked about inexpensive bricks made out of tunneling rock since 2018, and in true Elon Musk fashion, he called them Boring Bricks. Musk had stated that the Boring Bricks would cost 10¢ a piece, significantly lower than bricks on the market.
Besides the Boring Brick’s material and affordable price, another intriguing feature about it would be its durability. When Musk introduced the Boring Brick, he emphasized its strength. “[Boring Bricks are] Rated for California seismic loads, so super strong, but bored in the middle, like an aircraft wing spar, so not heavy,” Musk said later in a tweet.
Markham wanted to put Musk’s words to the test and compared his Boring Bricks with four traditional alternatives. He bought an average red clay brick for 53¢, a used clay brick for 58¢, a cinder block brick reinforced with steel for 71¢, and a normal cinder block brick for 43¢.
For his durability test, Markham dropped each brick from different heights until they broke into pieces. For the first test, he dropped them from chest-level and the Boring Brick passed with no problem. The 71¢ cinder block brick reinforced with steel passed without any scratches, and the 53¢ red clay brick survived the first test as well with a slight chip in the corner.
Sadly, the 58¢ clay brick and 43¢ cinder block were eliminated in the first round after both broke in two.
For the second test, Markem went up a flight of stairs and dropped the bricks from about 10 feet above the ground. The remaining bricks all passed the second round relatively unscathed, except for a small chip on the corner of the red clay brick and a tiny one on the Boring Brick.
In the third test, the Boring Brick proved its durability once more, surviving a fall from about 12-14 feet above the ground with just another slight chip. By this time, the only other brick that survived Markham’s durability test was the cinder block brick reinforced with steel, which cost over 7x the price of the Boring Brick.
The What’s Inside? host’s test was undoubtedly fun and did demonstrate the durability of the Boring Brick at some level. However, the durability of bricks is usually tested through compression and there are other factors to consider when judging a brick’s quality.
Nevertheless, Markham’s video managed to show that the Boring Brick is a viable product and could be another potentially revolutionary idea from Musk. At its price point, Boring Bricks could change the construction and housing market. Markham paid a little extra for his Boring Bricks but didn’t seem to mind since they were commemorative pieces. He paid $200 for each Boring Brick and gave one of them to a friend.
Elon described Boring Bricks as “lifesize LEGO-like interlocking bricks” in the past. Based on the bricks that Markham acquired, it appears that Musk is sticking to his plan. The Boring Brick had two holes in the center reminiscent of Lego bricks, with “The Boring Company” written in the middle. These should allow for easy buildouts for construction projects, as the bricks are optimized to be laid with relatively little effort.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
