Auto-Drive is Geting Closer Thanks to Nissan

Nissan is integrating "Intelligent Cruise Control" which uses GPS to control the car's speed when approaching curves. See "Nissan's GPS enabled cruise-control foreshadows robot car". So when do we get auto-drive is my question. It is not a matter of technology but more a matter of when. The technology is already here. Come on Honda or Toyota, you can do it!
