Keeping the next generation automobiles in mind, iPhone manufacturer Apple Inc is concentrating on technology for self-driving cars, Chief Executive Tim Cook said. The company is focusing on autonomous systems, Cook said. "We're not really saying from a product point of view, what we will do ... it's a core technology that we view as very important," Cook said. A late entrant to the self-driving race, Apple secured a permit in April to test autonomous vehicles in California and has recruited dozens of auto experts. Earlier, Apple had had been seeking to build its own car, before recalibrating those ambitions last year to prioritise the underlying technology for autonomous driving. If the reports are to be believed then the iPhone maker had hired more than 1,000 engineers to work on Project Titan, as the car team is known internally, after it started in 2014.
