A pair of Teslas caught fire and were destroyed in San Francisco over the weekend just weeks after a self-driving electric vehicle was torched in a nearby neighborhood, according to authorities. Over a 30-minute period early Saturday morning, the San Francisco Fire Department responded to two separate vehicle fires in close proximity, on Bonifacio Street near Mabini Street and Shipley Street between 4th and 5th streets, officials said. The department extinguished the fires and began investigating at least one as a suspected arson. Video obtained by CBS News Bay Area showed the origins of the second fire: a person setting the white Tesla Model Y ablaze around 12:45 a.m. The unidentified person ignited a fire in one of the wheel wells, causing the entire vehicle to go up in flames within minutes, the video shows.

Just 27 hours after launching a Tesla Roadster into orbit around the sun, Elon Musk has turned his gaze from the red planet to the blue one, where he's trying to get a different sort of project off the ground. "If we can send a Roadster to the asteroid belt, we can probably solve Model 3 production," Musk said on an investors call today. What 400,000-odd potential customers and more than a few investors want to know is, how much more time? The $35,000 Model 3 sedan is crucial for Tesla's success. It's the car meant to take electric cars mainstream--and Tesla into the ranks of the big automakers. Yet the Silicon Valley company just released financial figures revealing that it ended 2017 with its largest quarterly loss ever: $675 million.
