There are a LOT of things that the Street View trucks catch that aren't good if kids see them. I went to check a few of them out yesterday but they had already been replaced. Also there used to be a few instances where the camera on top of the truck was either struck down by a low bridge or pooped on by birds, but those were gone too.
Yeah, but one of them was just plain blurred out. It was two guys in viking gear fighting each other and when you're right in front of them it's blurred out but if you go down the street then you can see them clearly.
Some of them were pretty old so I guess they were replaced when they did their rounds again, although it only seems that took place in highly populated areas like the US. Most of the stuff in rural areas of smaller countries was untouched.
