I ****ing love google street view. In May/June or so last year they had almost all of Florida (I know specifically florida cos of the ex showing me his parents house and virtually driving me round his home town) and loads of places in the states, but hadn't gone to rural maine. By December, they'd got as far as adding rural Maine. By August last year they had about 95% of New Zealand and a load of Australia, some towns in northern France and other isolated places round europe. They now have a load more of Australia and tons more of Europe.
In July last year the google street view car drove past me on Marylebone road (the one bit of the MR that's not on there! boo) so that's when they did London. You can see my flat (I was at home, the window is open) and my car parked on the street, in two different places, owing to the two different days/time of day they did it. The US have been able to access UK places on google street view for about a month or so longer than we in the UK have (I know this, cos my friend in Maine found my flat on it before i could access it!).
The ariel photos on google were done years ago. This, I can tell from the colour of parents' garage door and cars parked at my mums work. As someone else said, the ariel photos are more of a security risk than the street view images as they show potential access points and escape points from above, although even then, as they're so old, the information is potentially very out of date.
As for the invasion of privacy lark, pur-leeese you can walk down the street and see all of that! The pictures are 9 months old, stuff changes, people move, change cars, change windows, change locks etc. Do you want to take out an injunction against anyone from walking past your house?!
If you want to know what places do and don't have street view. Go to googlemaps, zoom out so you can see most/all of the world on one page. Get the little orange man, drag him on to the map, wait, see which places turn blue. They have street view.
