To say the least, Los Angeles has a reputation as a car-friendly (and/or dominated) city. Some people are hoping to change that:

The most explicit attempt to capture the shift in the zeitgeist is the notion of the “Third Los Angeles,” a term coined by Los Angeles Times architecture critic Christopher Hawthorne. In an ongoing series of public events, Hawthorne has proposed that L.A. is moving into a new phase of its civic life. In his formulation, the first Los Angeles, a semi-forgotten prewar city, boasted a streetcar, active street life, and cutting-edge architecture. The second Los Angeles is the familiar auto-dystopia that resulted from the nearly bacterial postwar growth of subdivisions and the construction of the freeway system. Now, Hawthorne argues, this third and latest phase harks in some ways back to the first, in its embrace of public transit and public space (notably the billion-dollar revitalization of the concrete-covered Los Angeles River). Hawthorne’s focus is not specifically environmental. But a more publicly oriented city also tends to be a greener one. This is partly because mass transit and walking mean lower carbon emissions. And more broadly, willingness to invest in the public realm tends to coincide with political decisions that prioritize the public good, including ecological sustainability…

On all of those fronts, there are signs of change. One of the most obvious counter-examples is CicLAvia, the kind of phenomenon that makes Jacobs acolytes swoon. Launched in 2010, it’s a festive event during which miles of streets are closed to cars and swarmed by bikes. Taking place every two to three months, and rotating among different neighborhoods (Echo Park, the Valley, South L.A., etc.), each occasion attracts a diverse crowd of tens of thousands of people. They are the type of feel-good events—some might even call them utopian moments—where strangers smile at each other and ordinary life feels suspended. Traffic lights blink, and even cops whiz by on two wheels, wearing endearingly dorky helmets. In every sense—the car-shunning, the enthusiastic proximity to strangers, the exploration of different parts of the city—CicLAvia is antithetical to the guarded, privatized, auto-carved Los Angeles of lore.

Early Los Angeles was a streetcar leader and the metropolitan region today is the densest in the United States (meaning that it is spread out but it is pretty dense in its spread). Yet, truly transforming the region away from reliance on cars requires a lot of work including: building mass transit (buses might be best given the roads but building light rail and subways could be more powerful in the long run even if they are incredibly expensive at this stage), approving denser development (not an easy task in a region where property values are incredibly important), developing a vibrant downtown that also includes housing units, and perhaps finding ways to deincentivize development on the metropolitan fringes.

Perhaps the best thing that could happen to Los Angeles in this area of green sustainability is the continued improvement in vehicles. Radically transforming Los Angeles may be a hard sell but slowly increasing MPG, introducing new power sources (fuel cells, hydrogen, etc), getting older cars off the road, and eventually having autonomous cars could be very helpful. Of course, those changes are not ones really made at the city or metropolitan region level but the guidelines of the state of California and the federal government may just go a long way.
