So I watch people use maps, and one feature that I like a lot if the callouts for the individual driving directions. Here, do this...go to this page (opens in new window):
Google Maps - from el camino and castro street, mountain view, ca to 800 Amphitheatre Pky, Mountain View, CA 94043
And click on the 4 link for the direction, "Turn right at Stierlin Road". Note the callout. All hail maps.google.com. And to answer a recent question I was asked about maps, in fact there are no deals on file with the devil for the UI.
