- We try to only run GPS when your next calendar event is coming up.
- Right now we have an application-wide setting that says, "Add X minutes to my travel time." We're hoping people will use that to accommodate the fact that they have to walk to their car, find parking, etc. Eventually we'll make this configurable for each event.
- Yeah, traffic estimates aren't 100% accurate, but they're better than crossing your fingers and hopping in the car. :)
