Over the period of eighteen months, Apple's autonomous vehicle fleet has gone from just three to almost 70 and now has the third largest fleet following GM Cruise and Waymo. While Apple is struggling with its maps; a key element to autonomous driving systems; it is building maps in-house and from ground-up now. The growth in autonomous fleet provides some evidence that Apple is serious about rebuilding high quality maps, with major motivation being autonomous cars rather than just iPhones. With a recent leak of more than 5000 strong teams working on it and hiring of Waymo's senior engineer Jaime Waydo, it remains to be seen how soon the world's richest company can leapfrog its rivals. A space to closely watch. – Neil Shah
