Tesla Cybertruck
While we do not know as much about the Tesla Cybertruck as we do about other vehicles, it does involve one of Musk’s biggest blunders. When introducing it, he claimed the windows are bulletproof. He likely was not briefed on the model used for the display.
Those obviously don’t include all the bells and whistles of the Cybertruck at launch. The windows are certainly bulletproof for all Cybertrucks as Musk said, the model used for his talk about it was not. When he attempted to prove the strength of the windows, he asked Franz von Holzhausen to attempt to break one.
Franz asked if Musk was sure before he did it, when Elon said he was, Franz actually broke the window. This is why you always ask your team if the display model is 100% the vehicle one sees at launch. While Franz is one of the main designers of the Cybertruck, a few others also contributed to the design and other engineering aspects of the Cybertruck.
Ian Kettle, Sahm Jafari, David Imai, and Ivan Lampkin all contributed to its design and development. While Musk has been talking about Tesla making an all-electric truck for years, he’s not the mastermind behind it. Moreover, it is not going to be available to buy until 2023.
