The other day i stumbled upon a car driving around the city with a huge sensor apparatus on its roof.
The sensor hardware included LiDAR laser remote sensors, 360 cameras, a very accurate satellite positionning system, and a bunch of other hi-tech gadgets. The system was active and capturing huge amount of data. This a real, and Big Brother is watching you.
It appears that Navteq is doing the mapping and street view photography for the Microsoft Bing search engine.
