Good choice
Erlang could have worked well too.

...which shouldn't be a problem for Google!
A bit of code that knows the distance between photo A and B should be able to produce a composite image that contains only static elements - therefore blurring out most people and eliminating most problems.
An easier way on a small scale would just to take long exposures so people are blurred out from the start - but of course that won't work too well from a moving vehicle. Perhaps a squad of cyclists with tripods could be a low-tech fix. :)
