Re:Show HN: GPS + Calendar + Traffic = always on time by justinwi on Monday March 05, 2012 @04:36PM (#3668458)
Thanks for sharing. Our take:

- 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. :)

That could be a problem. Perhaps you want to run it near the last appointment? This is a complicated problem.

Some things are better done earlier than later. In "new development" cities, this is okay, but in more complicated locations it will be a serious per-appointment issue. In a time when people say the first mover advantage is an illusion, getting ahead of the UX game could mean everything.

Just remember to err on the side of early. ;-)
