In 2019, Tesla’s big Cybertruck reveal turned into instant meme history when a live demo of its “armor glass” went hilariously wrong. Chief designer Franz von Holzhausen threw steel balls at the truck’s windows — and both shattered on stage. Elon Musk laughed it off, Tesla leaned into the chaos with merch and tweets, and over 200,000 preorders rolled in within days. Nearly six years later, Franz calls it “marketing gold.” Sometimes, the best pitch is a broken window and a sense of humor.
