Many people use waze on a daily basis as a way to avoid traffic. We know how to get home or to work, and sometimes our work places have multiple entrances. These entrances don't always trigger waze that you have arrived, so even once I'm in the building, suddenly I hear waze trying to route me through the office hallways from my pocket.....

A new feature called "proximity routing" that the user can enable for their "home/work" locations would take care of this problem. Once the driver gets close, waze would indicate you have arrived and go into sleep mode. Alternatively, the sleep could be delayed until the external power source is removed, and thus waze can use that to mark where you parked.

I say home/work as the application of the feature as they are the most common usages, but there's nothing stopping the addition of a per-destination setting for favorite locations or when putting in a route to enable "proximity routing" for that trip.
