Washington, DC(CNN) Frustrated Tesla owners continue to wait for "full self-driving," an expensive and long-delayed software feature that isn't even guaranteed to help their cars' resale values. Some of the company's earliest backers of the "full self-driving" option are even beginning to lose faith in the promise of ever enjoying a truly autonomous Tesla. Years-long delays, buggy beta software, and the risk of no return on their investment in the option package have left some Tesla owners disappointed. Tesla CEO Elon Musk's prognostications, and Tesla's actual reality have diverged so much that some owners describe to CNN Business that they've lost confidence in his predictions. Some otherwise satisfied Tesla owners describe feeling duped into buying "full self-driving" ahead of its polished release, because Musk warned that the price would increase.

Eric Dishman is making a cup of tea-and his kitchen knows it. At Intel's Proactive Health Research lab in Hillsboro, OR, tiny sensors monitor the researcher's every move. Radio frequency identification tags and magnetic sensors discreetly affixed to mugs, a tea jar, and a kettle, plus switches that tell when cabinet doors are open or closed, track each tea-making step. A nearby computer makes sense of these signals; if Dishman pauses for too long, video clips on a television prompt him with what to do next. It's all part of a growing effort at Intel and other labs around the country to develop ways to help the elderly, and others who need assistance with everyday activities.

Most people have heard about self-driving cars, with companies from Google to Honda developing autonomous vehicles. But driverless technology could be going beyond cars, with the testing of a self-flying helicopter. A Sikorsky S-76 commercial helicopter has now successfully taken off and flown autonomously 30 miles, before landing itself safely. The helicopter in the trial was the Sikorsky S-76 model which used Sikorsky's MATRIX system The Sikorsky Autonomy Research Aircraft (SARA), used Sikorsky's MATRIX system. This is the same system that is use in the Optionally Piloted Black Hawk (OPBH) Demonstrator.
