After1 the mysterious Google Street View mapping vehicle went by our house on Tasso St in Palo Alto, it went by a PASCO garbage truck on N California Ave.
The top of the cab of the garbage truck is clearly visible in the second photo.
I think it's a van with a camera on a stick poking out the top.

1 Or before? It's kind of fun to try to puzzle out the direction and trajectory of the mapping camera vans from the images in the Street Views. Several photos are taken between each intersection, and they're taken in multiple directions. Usually it's not too hard to decide which direction the mapping van was travelingone locates a moving object in a photo (usually another vehicle, or person walking on the street), moves forward a bit on the map, and then turns around to see if it's moved in the time-positive direction or not. But at each intersection, the question arises: did the van go straight on through, turn, or what? Maybe more than one van was involved? If so, how to tell?
