Tesla founder Elon Musk suffered an embarrassing blow when his bulletproof truck - which supposedly features ''armoured glass'' - was smashed by a metal ball at a live demonstration, The Sun reports.
The electric motor, which can go 500 miles on a single charge, was unveiled at a launch event in Los Angeles.
Check out the awkward moment below:At the event, Musk encouraged people to hit the truck with sledgehammers in a bid to show off its apparently impenetrable exterior. He even showed footage of the six-seater withstanding bullets from a 9mm handgun, a feature usually only found in military vehicles and armoured state cars.
But it seems that being struck by a metal ball thrown by Tesla design chief Franz von Holzhausen was all too much for the truck - as impact completely shattered two of its windows.
"Oh my f***ing God maybe that was a little too hard," Musk said in response to the unexpected fail, before adding that there could be some room for improvement.
"We threw wrenches, we threw everything, we even literally threw the kitchen sink at the glass and it didn't break," he continued. "For some weird reason it broke now, I don't know why. We'll fix it in post."
Needless to say, plenty of people took to social media following the gaffe - just to rub salt in the billionaire tech mogul's wounds.
"'It's like redneck RoboCop designed a truck", one person wrote on Twitter, while others suggested the vehicle could have been designed by a four-year-old.
"Somebody's getting fired," another added.
"I think god might be giving Mr Musk a hint that he has possibly lost his golden touch," wrote a third.
But not everyone took the opportunity to roast Musk, with a number of Twitter users taking to the platform to praise the design of the Cybertruck.
"Apparently, I’m the only person who thinks the Cybertruck looks fire. I love it," one person shared.
"Solar Powered tonneau cover?" added another. "Please tell me yes having the ability to use #cybertruck like a generator having continuous charge is a musk!"
Others agreed that that the live demonstration was unfortunate but still insisted that the vehicle was of a superior make.
"A normal window would have the ball go right through," one person explained. "So I'd take the win. Though this is one of the cases where testing in a lab and testing on the street produce different results."
A release date for the motor is yet to be announced. It is, however, expected to be on the roads by the end of 2021 with a price tag of just $39,900.
