I could be wrong but I think that HDRadio is not in fact going to give us the greatest resolution the technology is cappable of. Digital radio broadcasts will be less prone to inteferance because you will either have the signal or not. It will allow for greater bandwidth but this will (just like HDTV broadcasts) be divided into multiple channels of content (three broadcasts using the bandwidth given for one broadcast) and surround sound of sorts (further dividing the available bandwidth).
No more listening to that faint NPR station through the static until you have driven out of the state.
