IEEE Spectrum [ieee.org] (doesn't appear to be paywalled) carries an article about Nissan's self-driving feature.
Nissan is about to offer a semiautonomous feature that's quite like Tesla's Autopilot. Not only does it sound like it - "ProPilot" - it also depends on a mono-camera sensor and on Mobileye [mobileye.com] processing.
