Instead of promising to deliver a certain number of EVs and energy products by the end of the year, Tesla said, "It is difficult to measure the impacts of shifting global trade and fiscal policies on the automotive and energy supply chains, our cost structure and demand for durable goods and related services." Tesla said it grew its "service area and fleet count" for its Robotaxi service in Austin, which involves safety drivers on board, and launched its Bay Area ride-hailing service.
