Why would it be ok for Apple to diversify by entering the car making business, while Tesla gets bombed for wanting to integrate Solar City? Anyway, looks like Apple is not doing the iCar anytime soon according to 'reports' of people on the project being fired.
Same can be said for Google making self driving cars while being a search engine commpany. What about Amazon the book seller that everyone thinks they are, what about all their cloud infrastructure solutions?
