LOS ANGELES — When the people whose houses hug the narrow warren of streets paralleling the busiest urban freeway in America began to see bumper-to-bumper traffic crawling by their homes a year or so ago, they were baffled.
When word spread that the explosively popular new smartphone app Waze was sending many of those cars through their neighborhood in a quest to shave five minutes off a daily rush-hour commute, they were angry and ready to fight back.
They would outsmart the app, some said, by using it to report phony car crashes and traffic jams on their streets that would keep the shortcut-seekers away.
Months later, the cars are still there, and the people are still mad.
"The traffic is unbearable now. You can't even walk your dog," said Paula Hamilton, who lives on a once quiet little street in the Santa Monica Mountains in a neighborhood called Sherman Oaks.
Hamilton's winding little road up the low-slung mountains that separate the city's traffic-clogged San Fernando Valley from its equally traffic-clogged west side is now filled each weekday morning with a parade of exhaust-belching, driveway-blocking, bumper-to-bumper cars.
So is practically every other nearby street that parallels the busy Interstate 405 freeway.
On the other side of the mountain, where cars cruise down roads into tony Brentwood, traffic has also been the hot topic of late, with several people telling each other they will fool the app with their phony accident reports.
