I use Waze in my car every day to and from work. Because of the battery drain on the iPhone while using waze, I keep it plugged in at all times as well. This makes it difficult to place the iPhone in my cupholder.
The ideal solution would be to allow the iPhone to be upside-down in the cupholder with the charging cable coming out of the top, simply auto-rotate the display to match the orientation.
This is a feature in some of the competing navigation apps for the iPhone, and I'd love to see it in Waze.
