I love Waze, the GPS/traffic app and use it all the time. And it has been a blast to try out some of the voices they offer — from boy band to British to C-3PO. This is the best, though. For a limited time, Waze-ers will be able to find their way under the guidance of the greatest voice of all: Morgan Freeman, on honor of the release of his new film, “London is Falling.” He will make every trip to work or the grocery store seem like a grand journey, or even a March of the Penguins!
