ELON MUSK: "Tesla full-self driving software, which is really just AI and cameras - we don't use radars or lidar or anything like that. It's really trying to drive the car in the same way that human drives the car, which is human drives the car primarily with vision and with a biological neural net, that we take the same approach with our vehicles, which is a digital neural net, and cameras, and we expect this approach to ultimately be at least an order of magnitude safer than humans driving. It is quite magical, because the car feels like it is sentient. It feels actually feels like it's alive. We already have some vehicles operating with no people inside and no safety monitors in three cities in Texas, and probably will be widespread in the US."
