Uber and Volvo have turned a number of XC90s into self-driving SUVs in the City by the Bay. It's an extension of the program the two companies tested in Pittsburgh earlier this year. Volvo says that while the overall goal is to, "build base vehicles that can be used to develop fully autonomous driverless cars." Mårten Levenstam, vice president product planning at Volvo Cars, said in a statement that, "The promise of self-driving ride sharing is becoming a reality. Volvo is proud to be at the forefront of the latest developments in the automotive world alongside our partners at Uber." For now, the cars have to have an Uber engineer on board, but Uber drivers, did you hear that?
