Tesla’s electric vehicle registrations in California fell by over 15% in the first quarter, according to CNBC. The California New Car Dealers Association cited an aging product lineup and backlash against Musk’s political role as drivers of the decline, including his leadership of the Trump administration’s Department of Government Efficiency. Tesla’s California EV market share dropped to nearly 44% from over 55% a year earlier. Tesla said retooling production lines for the refreshed Model Y at four factories caused several weeks of lost output during the first quarter.
