Automatic switch between sleep and unsleep mode
It would be great (for saving autonomy) having a mode which turn the device screen into sleep mode (if Waze is active on the screen) and come back into active mode before some interesting action, such as a junction, an off ramp to drive, or eating roadgoodie. In the best case, the time the screen become active again would be dependant of speed.
