The Cybertruck is a real, mass-produced vehicle: Tesla sold close to 39,000 in the US in 2024, making it the best-selling electric pickup in the country that year and one of the best-selling EVs overall. It pioneered a stainless-steel exoskeleton, an 800-volt-class architecture and giant structural castings — manufacturing risks no legacy automaker would take. The honest caveat: demand cooled sharply afterward, 2025 sales fell well short of the enormous early reservation hype, and it is one of Tesla's weaker models on reliability surveys. So "didn't live up to Musk's biggest predictions" is fair. But a pickup that sells tens of thousands of units and tops its segment in year one is not a "flop" by any normal definition.
