Of all the schemes Google has dreamt up over the years, Street View has got to be one of the most controversial.

For those not familiar with the idea, Google are taking photos of every street in pretty much the whole world, and integrating it with Google Maps. Naturally, several privacy groups are up in arms at the idea, even though Google have agreed to blur faces and remove people if they request it.

But blurring isn’t Google’s only problem. In what may become a test case, a couple in Pennsylvania are suing Google for publishing pictures of their house, as it is on a private road.

In a statement to court, Google said complete privacy does not exist, but have since said that their remarks have been taken out of context. Google clarified this to me in the following statement:

“There’s been some misinterpretation concerning our response to the Street View suit… It should not be interpreted as a blanket statement on our views towards privacy. To be clear, Google respects an individual’s right to privacy. We have privacy protections built into all of our products. For example, we blur faces in Street View and we offer easy-to-use removal tools so users can decide for themselves whether or not they want a given image to appear in Street View. It is unfortunate the parties involved opted to pursue litigation instead of making use of these tools.”

This problem will be far greater for Street View in the UK due to the very high number of private roads. There are around 40,000 in the UK, according to Private Roads Services. Although it’s hard to quantify the number of public roads in the UK, I estimate there are around 100,000 streets in London (according to a quick calculation counting the entries in the London street atlas).

Google said its policy was to not photograph private roads, and that its drivers were trained to look out for them. Which I think means not driving past a sign saying “private road”. But a spokesman admitted that mistakes have been made, and they would be more careful in future. “We made the error of photographing the approach road to a military base in the US,” said the spokesman. “We learnt from that.”
