If you’re looking for hints that Apple might deliver on its long-rumored plan to develop its own car, a significant one landed this week after it emerged that Doug Field — Apple’s former VP of Mac hardware engineering — has rejoined from the company after a spell with Tesla. John Gruber at Daring Fireball broke the news of Field returning to Apple following five years at Tesla where he oversaw the production of the Model 3. Apple confirmed in a statement to TechCrunch that it has rehired Field, but it declined to give information about this role.
