Directions miss this one

I am sitting at Yahoo!’s hack day. The speaker is talking about mapping and direction API’s. He is talking about the culture sensitivity about “landmark” obsession of Indian drivers also :-).

I have used maps on internet ever since they became available – and as such, I worked with GPS/GIS in 1995, even before Internet spread so deep.

All directions tell you where you want to go. I raised a point just now.

A key point is missing in “good direction” is, “If you have reached point X on this road, you have gone too far. Just take a U turn and come back.”

Why don’t they think of this?
