It turns out that Twitter is an excellent place for finding Street View sightings. Just searching for "Google Street View car" has revealed that people have apparently recently seen Street View cars in Los Angeles, New York, and Austin–three locations that haven't been reported yet! Since regular blog posts can't keep up with this, a new widget has been placed on this blog's sidebar, "Twitter Car Sightings". Hopefully, it will help us keep up with locations not covered by the media. I'll save the regular blog posts for media coverage.
So, get ready for updated imagery in the United States!
