Tesla Suffers Broken Glass Mishap During Chaotic Cybertruck Launch

Tesla's live demonstration of the Cybertruck's indestructible windows didn't appear to go entirely to plan. A metal ball managed to shatter the glass.

The big reveal of Tesla's electric pick-up went embarrassingly wrong when the supposedly impact-proof windows smashed, leaving a flustered Elon Musk to flounder through the rest of his presentation in front of a badly damaged vehicle. The Tesla co-founder unveiled the all-electric battery-powered Tesla Cybertruck in California on Thursday, daring staff to hit the vehicle with sledgehammers and showing a video of it withstanding bullets shot from a 9mm gun.

The industrial-looking Cybertruck -- covered in the same steel alloy Elon Musk plans to use for his SpaceX rocket -- will have a starting price of $39,900 and can go from 0 to 100 kilometres (62 miles) per hour in about three seconds, the Tesla chief executive claimed.
