There isn't a ton of value add in having daily updates to street views (things don't change that frequently), but there would be a huge increase in expense. I don't know the exact number of google street view cars, but there are way, way, way fewer than there are USPS trucks. Outfitting lots of USPS would add a ton of expense to the equation. As a side note, I am curious what fraction of houses they actually drive by each day. In many residential areas it seems common for drivers to park the delivery car while they walk around the block with the mail. Still, it seems clear the coverage is pretty substantial. Edit: this post indicates an October 2012 number of around 250 cars, just to give a sense of scale.
