The biggest difference is that with pretty much every car that's not a Tesla, the driver still needs to drive the car. That's true for the Tesla, too, but "full self-driving" makes it sound like it's different. Mercedes brought out their first actual self-driving car a few months ago. Unlike driver assistance, where the driver is expected to retain control at all times, it will give at least ten seconds notice -- so you're allowed to take your hands off the wheel, read a book, or watch a video. But it will only let you turn it on in very restricted circumstances.
