The wits at Lego, who designed their own answer to it, the Brickmobile (see above).
The toymaking giant tweeted out a moodily-lit image of a classic Lego building block on wheels and bragged that it is "guaranteed shatterproof."
That was the dig—it was aimed squarely at Elon Musk's biggest embarrassment from the Cybertruck unveiling when he bragged on the truck's "Armor glass." He then had one of his engineers test the supposedly shatter-resistant windows.
His assistant threw two large steel balls at the driver's side windows and, well—they definitely weren't shatterproof. Musk's facial expression in the photo above kind of tells the story.
While Lego didn't go so far as to make any kind of demo reel illustrating the Brickmobile's toughness, many people were quick to note that the little bricks certainly feel solid enough when you step on them in the dark.
Expert Lego builder Peter Blackert took the implied challenge a little more seriously and went the extra mile, building two different renderings of the actual Cybertruck.
That's more like it.
Musk hasn't responded to Lego, but he did tweet video of a test in which the Cybertruck pulled a running Ford F-150 uphill—proving it could handle the kinds of heavy hauling jobs it was designed for.
Elon Musk might be able to save face if he put his mind to figuring out how to make plastic toy building blocks that aren't pure torture on parental feet.
