As a stunt, Google has wrapped subway trains in New York City with ads for Google Maps. Inside, ads give specific directions to tourist landmarks like Madison Square Garden. Unfortunately, they misplace Grand Central Terminal by several blocks, directing people to subway lines which do not run through the station. A mistake we can see someone sitting in a cube in Mountain View making — but doesn't Google have a large New York office full of employees who might have been called on to vet the ads in their 20 percent time?
