In 2023, Tesla CEO Elon Musk promised that his EV maker's upcoming Cybertruck would sell like hotcakes, delivering between 250,000 and 500,000 units per year once the company hit its stride. But over two years later, Tesla hasn't even gotten close, in yet another instance of Musk vastly overpromising while severely underdelivering. In reality, the carmaker's pickup truck has flopped hard, not even selling 20,000 units this year.
