Which Waze LA?

The smartphone app called Waze has been helping more and more Los Angeles commuters find alternatives to grinding along at a snail's pace on busy freeways. That sounds great unless you live in a formerly quiet neighborhood of narrow streets now crowded with passing cars. Is it a real answer to heavy traffic or just making it worse in more places?

Also, why shutting down freeways may be the appropriate way to protest racist police and the balkanization of LA and other American cities.
