In an attempt to revolutionized the traditional auto industry by rolling out its self-driving car manufacturing cars, Apple Inc outlined a plan to train operators of self-driving cars in documents submitted to California regulators earlier this month, the latest clues to the company’s autonomous vehicle technology aspirations. Apple was granted a permit to test self-driving cars on April 14 by the California Department of Motor Vehicles but the company has never said anything about its plan. The state released 41 pages of Apple application documents to Reuters that give some clues about the company’s highly secret self-driving effort, which it has never openly acknowledged. The iPhone maker joins a long list of carmakers, start-ups and technology rivals, including Alphabet’s Waymo, that are testing cars on state roads. Apple is looking for new hit products and autonomous car technology is expected to revolutionize the traditional auto industry. As part of the application, Apple included a 10-page training plan that appeared to be related to operators taking back manual control of the car during automated driving exercises of the system, which it calls a development platform. The plan includes a document called automated system: Development Platform Specific Training Overview“whose objective is “to train safety drivers in various automated driving conditions.“ “Development platform will be controlled electronically (e.g. joystick) and safety drivers must be ready to intervene and take control,“ the document reads. Days after an error led to false iCloud cancellation emails sent to subscribers, Apple has followed up with another note apologising for the bug and reassuring them that their plan remains in good standing. On Wednesday, a number of iCloud users received messages saying their subscription was discontinued. The bug appeared to mostly affect 50GB tier subscribers, a report on Appleinsider website recently claimed.
