Do a search in Live.com or MSN.com, and as of today, if you type in an address you should get an inline interactive map as the first answer, according to the Virtual Earth / Live Maps blog.

The new Instant Answers feature extends to traffic information as well, for cities that feature it.  Typing "traffic Seattle", or "commute Chicago" will provide instant traffic information, although the info will be a snapshot and will not update in real time on the search page (although it will in a sidebar gadget, of course).  The maps are fully interactive however, and pan, zoom, and even aerial imagery are supported. 

Metro area traffic currently supported include Atlanta, Boston, Chicago, Denver, Detroit, Houston, Los Angeles, Milwaukee, New York, Oklahoma City, Philadelphia, Phoenix, Pittsburgh, Portland, Providence, Sacramento, Salt Lake City, San Diego, San Francisco, Seattle, St Louis, Tampa, and Washington DC.
