The executive for Google feels that way because of a close-call he had while driving his S-Class.
Traffic had stopped in front of him, but Gundotra didn't notice. His Mercedes did, however, and the electronic nannies brought the car to a complete stop without a lick of input from Vic. He was so impressed with the technology that he decided to write the automaker a letter to thank them for installing the system into its cars.
That thank you comes from a source that understands software, so Mercedes decided to reach out to Gundotra. The Google exec agreed to appear in a commercial for Benz, and he wasn't paid for his participation.
