GPS Most Wanted Features

I found a couple of great comments on http://aplawrence.com/Opinion/my-next-gps.html that triggered some thoughs about making GPS systems smarter. I agree wholeheartedly. As a user, you expect your electronuics to adapt to you, not the other way around.

When you are on a known route, maybe at the end of an unknown place after you hit "go home" shouldn't it stop giving you turn-by-turn directions? Obviously you know where you're going, since you've taken this route several times and your GPS knows it.

I've also seen some of the in-car GPS systems do not allow you to operate them while you're in movement. I understand the safety concerns. However, the airbag and the annoying "fasten your seat belt" chime are smart enough to turn themselves on when they detect passenger weight. Shouldn't the GPS do the same an allow the passenger to operate it?

These are a couple I can think about. Any other thoughts of how to make a smart GPS?
