Tesla CEO Elon Musk unveils bizarre cybertruck electric pickup but botches live demo

Tesla CEO Elon Musk has been left embarrassed after the glass on his new electric'Cybertruck' was smashed just after he boasted about it being'shatterproof'. During the announcement of the truck - which looks like a armoured vehicle with angular sides - Tesla design chief Franz von Holshausen tried to prove the glass was'shatterproof' by throwing a heavy metal ball at close range. Musk was heard muttering'oh my f***ing God' when the glass smashed. It is the second embarrassing mishap for Musk in as many days, after the first full-size prototype of the SpaceX Starship rocket exploded during pressure testing on Wednesday. The Tesla Cybertruck is unveiled at Tesla's design studio Thursday in Hawthorne, California.
