Google's next iteration of its popular Maps app looks to be adding a whole bunch of new functions, if the recently released 9.34 beta is any indication. The big news is that the update could include text-based alerts informing users to parking shortages at their destination. This will allow you to account for not just enroute traffic but also fighting for a spot once you get there. It's not like Google can actively track open spaces so the service will more likely be based on the total number of spaces available in given area while taking into account time of day and nearby public sporting/concert events. Still, that's valuable information especially if you aren't a local.
