Will wonders never cease? Google now has both 'street' and 'traffic' views to add to their three other map views (road, satellite and hybrid.) In San Francisco and New York, and a few other cities, (not Boston) the street view will being up four angles of actual photographs of the location. It is a bit tricky to use - you have to use your 'human' icon and 'walk' to your location to bring up the street view. Not all streets are available in those cities, either.
More useful is the new traffic view. Is this new or have I never noticed? Wherever there is a traffic light (Springfield, Boston, Providence, etc.) the map will offer you current traffic conditions in red, yellow or green. I refreshed my screen and watched Westboro's traffic on the Pike change from a large red jam to moving green traffic. Pretty cool.
I recommend the Google Maps User's Guide as a place to start.
