Councilman Eric Garcetti once explained to a group of people that traffic is a sign, a good sign. A sign of a strong economy. If there was no economy, people wouldn't be traveling to their jobs, thus causing traffic.
"The maps together show that a lot of the jobs and the people are concentrated in different places. Thus, people have to drive to get where they're going." And that's one big reason why we have traffic.
