Tesla sales plunged 13% in the first three months of this year, the largest drop in deliveries in its history, as backlash against CEO Elon Musk and growing competition took a large bite out of demand for its EVs. Tesla reported Wednesday that it delivered 336,681 cars in the quarter, 50,000 fewer vehicles compared to the first three months of last year. The results were the company's worst sales in nearly three years. Tesla has faced protests outside its showrooms from those opposed to the actions of Musk in one of his other roles as the head of the Department of Government Efficiency, and the policies of Donald Trump's presidential administration. There have also been instances of vandalism against Tesla facilities, including its charging stations, as well as some cars. All these incidents may have discouraged some potential Tesla buyers from going ahead with their purchases.
