Well, they only re-drive most places every few years (Toronto seems to have 1-2 year gaps), so their own image sources won't necessarily have that data yet. Alt

Well, they only re-drive most places every few years (Toronto seems to have 1-2 year gaps), so their own image sources won't necessarily have that data yet. Although, you'd think that local business listings would also be a data source and would probably be up-to-date. Do they scrape retailers' sites to learn about store locations? Guess not but would have assumed so. Just wait for the self-driving car tests to ramp up. I think one of Google's early deployments will be a fleet of self-driving cars equipped to take streetview photos - this should enable something like weekly redrives of cities.
