Seems to me the Canuc have got it right.
Google broke the law, and the reason they have given is that it was an error on their part. However, no-one was harmed, no data illegally captured was used (and as others have said, I can see no use of using the data anyway, it's worthless to Google or to anyone else).
Google get a fairly stiff slap on the wrist, and some really bad press and they will have to tighten up their software release practices (and I can easily see how this rogue code got in to the street cars by accident - and anyone who cannot see how its could have happened obviously hasn't worked in the software industry for long enough or with big code/library sets - remember this is a google car taking pictures, not an airliner or power station control system)
Seems a fair result to me.
