The race between two key chip makers to put self-driving cars on the streets is getting heated.

And it's no less entertaining, involving the likes of BB8, a self-driving Nvidia car named after a droid in Star Wars, and the company's automotive supercomputer called Xavier, named after an X-men superhero.
