Angel investor Jason Calacanis, one of Uber's first investors, has a top pick to be the company's next CEO: Elon Musk. Calacanis said Friday on his web show "This Week in Startups," that a tie-up between Tesla and Uber would give Uber the autonomous driving technology it so badly needs and expand Tesla's reach into many more markets. "If those two companies were together, they would beat everybody at transportation," said Calacanis, who backed Uber in 2009. "They're on a collision course for sure." The only reason Calacanis is entertaining such a wild idea is that Uber is in utter chaos. It lost its co-founder and CEO Travis Kalanick to a forced resignation in June and venture firm Benchmark, one of the company's biggest investors, is now suing Kalanick alleging fraud and breach of fiduciary duty. In court documents filed last week, Kalanick called the suit a "public and personal attack" without merit. Uber, which was valued at about $70 billion in its last private financing, is operating without a C-suite and with nobody clearly in charge. Meanwhile, the company is locked in a court fight with Alphabet's Waymo unit that could thwart Uber's effort's to keep developing self-driving cars.

By merging with Tesla, Uber would get its new CEO in Musk and be able to keep Kalanick involved as a board member, Calacanis said. This is all far-fetched speculation. Tesla has a $58 billion market cap, but loses hundreds of millions of dollars a quarter. And Uber lost more than $700 million in the first quarter. While Silicon Valley may love the combination of two trailblazing transportation companies, it would likely be a very tough deal for Wall Street to swallow. Calacanis wants the company to get past this ugly patch as quickly as possible. He said the crisis embroiling Uber and its board is "very sad for me." On Monday, he posted a picture on Twitter from 2014, featuring himself, Kalanick, Benchmark's Bill Gurley and venture investor Shervin Pishevar, an early Uber backer who is trying to get Benchmark removed from the board in the wake of the lawsuit. In his tweet, Calacanis said the photo was "presented without comment," but he talked about the meaning behind it on Friday.
