I also find it interesting to look at things that 'used to be'. Like, for example, the picture below, showing one of the entrances to the old Dodge Main Plant in Detroit. The property is mostly owned by GM now (and mostly vacant), but you can still see the Chrysler logo on the tank.
I'm glad that my street is not yet mapped with the Street View. Wouldn't want anyone to see my Challenger on jack stands in the driveway or anything!
Another interesting feature...In certain views within Street View, you can rotate the camera downward and see the car they drove around while taking pictures. Seems like they've mostly eliminated that now, but when this feature first came out, you could always look down and see the camera bubble on the car.
