'Oh My F**king God': Elon Musk Stunned As Windows Crack On His 'Bulletproof' Cybertruck

Mary Papenfuss

The often surprising Elon Musk was stunned himself Thursday when two windows cracked during a demonstration of his futuristic, all-electric Cybertruck — which had been pitched as “bulletproof” and practically indestructible.

Longtime Tesla lead designer Franz von Holzhausen, following Musk’s orders, threw a small metal ball at the pickup’s driver-side window — and cracked it quite spectacularly after the vehicle’s unveiling in the Los Angeles area.

“Oh my fucking God,” Musk erupted as the audience gasped. “Maybe that was a little too hard.”

So von Holzhausen tried again, this time more softly lobbing a metal ball at a rear passenger window — and cracked it as well. There’s a “little room for improvement,” Musk quipped.

The stainless-steel angular vehicle inspired by the film “Blade Runner” “doesn’t look like anything else,” Musk boasted before the mishap. He explained in a tweet Friday that the window stunt had gone well in rehearsals.

Before the glass mishap von Holzhausen had pounded on the body of the truck with a mallet and failed to dent it.

Some on Twitter suspected that the shattered glass may have been a very successful publicity stunt. In any case, analyst Gene Munster of Loup Ventures told Bloomberg: “It’s classic Tesla. It’s poetic. I applaud the company for taking risks: This was not a boring presentation.”

Musk’s tastes have so far struck a chord with consumers. But his popular cars have also suffered glitches, including with the company’s touted autopilot system and links to accidents.

The Cybertruck will retail starting at $39,900. The reception on Twitter was a bit mixed. But “scores of customers” have already put down $100 deposits for the truck, which won’t be manufactured until late 2021 — at the earliest, according to Bloomberg.

Democratic presidential candidate Andrew Yang tweeted Friday that the “world needed a Cybertruck without knowing it.”
