Tesla's once-dominant hold on the U.S. electric vehicle market continues to erode, with its domestic market share now falling below 50% and trending toward 40%, according to Cox Automotive. The company's vehicle deliveries in the first quarter missed analyst expectations, declining from a year ago, as its aging lineup and Elon Musk’s polarizing political image weigh on demand. Tesla’s troubles are even more pronounced in Europe, where sales plunged 49% in April and nearly 40% year-to-date despite rising EV adoption across the continent, according to The Street. Musk claims that politically conservative buyers have replaced left-leaning customers who abandoned Tesla. Speaking at the Qatar Economic Forum, he insisted that the company continue seeing strong demand.
