I am "Waze Royalty" and a Waze map administrator for the greater Boston area and for a chunk of coastal Maine. Good program, as much for avoiding speeding tickets as for routing. It seems to use a more creative and responsive routing algorithm than other programs, but it has a strong bias for getting you onto big highways.
I like Waze, too.
Last night, Waze popped up a window saying "I found a better route!" and automatically rerouted me. It sent me down a very weird back road, and I thought "WTF? never again!"... until it dumped me out at the front of a very long traffic jam, which saved me a very long waiting in line experience. I gave up spending $20 a year on MotionX Drive in favor of Waze.
In the past, I've passed the suggestion to add the ability to report and display others' reported events (accidents, traffic, speed enforcement, etc), speed limits, weather and traffic conditions to Tesla.

I like @dsm363's idea about "pushing" a route. Sometimes, esp. longer journeys, I have a specific route I want to use that is tricky to enter. I'd like to be able to save that route as a personal Google Map and then load that map in the Model S.
One quirk - which the Tesla rep with me couldn't figure out either - is that the map app is in the "North Up" mode alone and couldn't be toggled to "Car Heading Up" (or whatever it should be called). I'm more comfy using the latter in nav systems.
Because the map system is based on Google Maps, I wouldn't expect it to have a car orientation setting the way a dedicated car nav system does. (I'm a North side up kind of person so it won't bother me).
Highly doubt it for a number of reasons. How would it know where you're going? Precaching that information while the car is off just so you see it at boot doesn't seem to be worth the effort. Id say, if it's a concern, pull up the maps app as soon as the screen loads and check your route ahead.
