That very futuristic F 015 concept vehicle from Mercedes-Benz won’t be available to regular people for at least 15 years — but it has already been spotted parked and crusing through the streets of San Francisco. Mercedes unveiled the “Luxury in Motion” vehicle at CES in January. It’s more of a symbol than anything: the type of thing Mercedes imagines we will use to commute to and from work in the future. But it’s clear, at least, that Mercedes is actually working on self-driving technology.
