Musk's Secret Plan to Curb City Traffic With Self-Driving ‘Bus’

Tesla’s Chief Executive Officer Elon Musk is working on a self-driving vehicle he says could replace buses and other public transport in order to reduce traffic in cities. But he’s keeping the development a secret.

“We have an idea for something which is not exactly a bus but would solve the density problem for inner city situations,” Musk said Thursday at a transport conference in Norway. “Autonomous vehicles are key,” he said of the project, declining to disclose more. “I don’t want to talk too much about it. I have to be careful what I say.”
