Do you live in California and have artistic inclinations? If so, Google has an exciting opportunity for you. Later this year its self-driving cars will be zipping around Mountain View, California adorned with artwork selected from among submissions sent in by the population at large. It is kind of like Google Doodles, only the "doodles" will be on the side of the self-driving cars for a month or longer, depending on how Google feels about it. The Internet giant will accept submissions soon.
