Cha, if that's why you're after the zoom level of 2, then you're going to be somewhat disappointed to know that you don't get to see anymore detail at 2 than you do at 6. The only thing that's different is that you get a bit more pinpoint accurate reference to your current location. Otherwise it doesn't show any extra detail. I've verified that around here several times just using the Google Maps API, and I live in a small town with some rather odd streets, and I haven't found any extra stuff available in the level 2 that isn't available in the level 6.
