It seems to me it would be useful (and a good use of Google's AI) to be able to state my "Need" to Waze and have it solve it for me. For example, I would love to be able to say:

1) Me: "Waze, I'm hungry":
2) Waze: "Of the 3 restaurants on your favorites list, I see the most convenient one is along your route in 6 miles, or, further along your route is Restaurant #2. Does one of those sound good ?

This would be much more convenient than trying to yell at Siri to find the "Nearest Fast Food", which is some arbitrary location usually not on my route.
