If it said Copyright 2003 then that would mean anyone could use that image as it was no longer under copyright. A copyright date does not have to be when the picture was taken.
Looking on Google Earth, my old car is on my driveway and I got rid of that about 5 years ago so not everything is really up to date. Saying that, when your taking pictures of the entire world, it probably will take a while.
I've seen Google cars in England but as yet there are no street views for England yet.
