These five patents hints at what an Apple car could look like

New York (CNN Business)Talk of a possible Apple car is back. Apple (AAPL) hasn't commented publicly on its plans for the project, nicknamed Titan, so it's not clear exactly what will come of the effort. Some who follow the company think it could release a whole Apple-branded, electric, self-driving car. Others think it's more likely Apple will partner with existing automakers to sell an operating system (iDrive, maybe?), self-driving tools or other technology. There are some clues available, though.
