You know that car that Apple may or may not be building? It may or may not have hired someone from Tesla to work on it. Cupertino's own has hired Tesla's former Vice President of Vehicle Engineering, Chris Porritt. Of the alleged hire, 9to5Mac wrote:
We are told by sources with knowledge of the matter at Apple that he joins the company as "Special Projects Group PD Administrator" – an intentionally vague title. Last year, Apple hired a senior engineer working on Tesla's Autopilot program, Jamie Carlson. He was also listed as a member of a special projects group.
Porritt has a background in vehicle dynamics and architecture. He is believed to have worked on Tesla's Model S and X vehicles. I don't want to jump to conclusions but it's starting to sound like Apple is doing something in cars.
