Tesla profit falls short again as Elon Musk demands investor patience

Tesla Inc reported its fourth consecutive quarter of disappointing profits on Tuesday, with CEO Elon Musk indicating that significant improvements are still some time away. The company will unveil a prototype of the much-anticipated robotaxi on October 10, but the actual product won't be available for a while. Additionally, a new, lower-cost car aimed at boosting sales won't begin production until at least the first half of next year.
