Google Maps: Damn Thats Cool (Part 87)

Ok, I hate to have two posts in a row on new Google related innovations, but I must say I thought this one was pretty cool. Nothing revolutionary, but just seems like a very nicely executed functionality on Google Maps that allows you to drag and drop routing as well as insert way points to very easily change routes and the corresponding driving directions on the fly. It speaks to a need that is seemingly so obvious, like selecting a new route if traffic is bad or you decide that you want to make a pit stop or two en route. Surprised that no one has done this before... but seems that some of the best ideas are ones that you end up saying 'why didn't I think of that?!"
