There is a story by Mike Swift at Mercury News with pictures of the streetview tricycle. Information was from Google's Daniel Ratner.

"... Google is using ungainly, 250-pound, 9-foot-long, human-powered trikes with a 7-foot stalk of cameras on the back."

"Google often hires soccer players and other athletes to pedal the heavy trikes, which have special gearing but are extremely heavy for a human-powered vehicle."

The Google Lat Long blog has some more coverage.

Google Street View cars driving resumes 3rd of March 2011 to the indicative date of 30th of November 2011 in Ireland (hi Tullamore!).

They are back in Spain and Sweden too.

Let me know when they're outside my house Tom!

No problem ;-)

Oh, Portugal is in the list too. (Faro, Castro Marim)
