SAINT PAUL - An eagle-eyed Internet user discovered the moment Google Maps and Bing Maps camera cars spotted one another - and one site censored the other. A Tumbr user revealed this week that the vehicles met on a Minnesota road in July and ended up with photos of each other for Google's Street View and Bing's Streetside map features. The Google photo shows the passing Bing car, while Bing's version features a white box over the Google car - but it's camera remains visible. Another shot from the exchange shows the uncensored Google driver giving a friendly wave to the Bing car. - Agencies
