Lockscreen Route View
After using the new maps on iOS 6 I could only come up with a little amount of good new features the maps app has. The most helpful one is that the route you are following is displayed on our lock screen, so you can lock your cellphone to avoid people to use your phone while using the gps to get to a please, and also to save some battery. So adding this feature of showing the route on the iPhone would be a great idea, just by the fact that on the road you want to have the information the quickest possible so you don't miss any exits or turns. Waze could show the whole screen you see (vehicule, speedometer, events, wazers)

Great news! It’s now available in Waze for Android in Brazil. In the meantime, make sure you’ve got the latest version of Waze to enjoy all the latest features.

This is the only feature that makes me want to use apple maps. I hate leaving the screen on the whole time and it's can be pretty annoying to go to the waze app constantly, especially if I'm controlling my music as well.
I used to think that only official apple apps could use the lock screen, but Pandora uses it just fine.
