Is an App to Blame for Neighborhood Traffic Jams?

There's a new voice in town, that of the smartphone app called Waze, which crowd-sources GPS signals from moving cars to guide drivers away from heavy traffic.  More and more LA commuters are devoted to Waze to find alternatives to busy freeways.  The downside is that narrow streets in some residential neighborhoods are now being turned into highways. That's according to Richard Close, president of the Sherman Oaks Homeowners Association. His neighborhood abuts the 405 Freeway in the foothills of the Santa Monica Mountains.
