There has been an increasing amount of speculation and conjecture recently amongst technology analysts who claim that despite Apple's recent record-breaking earnings call the Cupertino company could be in long-term jeopardy due to its lack of recent innovation. That level of doom and gloom has largely been dismissed by the wider technology community but it has managed to plant the seed in our minds of what Apple could potentially be working on next. According to multiple reports, Tim Cook's company could be looking at self-driving vehicles, a possibility that has gained some credibility thanks to a mysterious Dodge Caravan that has been spotted in and around the Bay Area.
