Smog and air pollution due to vehicles is a familiar sight in many large cities. Yet, Crabgrass Crucible suggests the fight against smog in Los Angeles did not target driving itself but rather automakers:

The ban on fuel oil easily found favor among antismog activists. After all, like the steps with which smog control had begun, it mostly targeted the basin’s industrial zones. Harder to swallow in Los Angeles’s “citizen consumer” politics of this era, even for antismog activists, were solutions that might curtail the mobility associated with cars. Consonant with national trends noted by automobile historian Thomas McCarthy, there was a widespread reluctance to question orthodoxies of road building and suburban development. Even the “militant” activists at the 1954 Pasadena Assembly only went so far as a call to “electrify busses.” By the 1960s, as motor vehicles were estimated to cause nearly 55 percent of smog, there were suggestions for the development of an electric car. Yet Los Angeles smog battlers of all stripes raised surprisingly few questions about freeway building. For many years, Haagen-Smit himself argued that because fast and steady-running traffic burned gasoline more efficiently, freeways were smog remedies. So powerful and prevalent were the presumed rights of Angelenos to drive anywhere, to be propelled, lit, heated, and otherwise convenienced by fossil fuels, that public mass transit or other alternatives hardly seemed worth mentioning.

Once pollution controllers turned their sights to cars, they aimed not so much at Los Angeles roads or driving habits or developers as at the distant plants where automobiles were made. Probing back up the chain of production for smog’s roots, local regulators and politicians established a new way of acting on behalf of citizen consumers. Rather than pitting the residential suburbs of the basin against their industrial counterparts, in an inspired switch, they opened season on a far-flung industrial foe: the “motor city” of Detroit. The APCD’s confrontations with Detroit car makers had begun during the Larson era, but quietly, through exchanges of letters and visits that went little publicized. In 1958, after the nation’s chief auto makers had repeatedly shrugged off Angeleno officials’ insistence on cleaner-burning engines, the Los Angeles City Council went public with its frustration. It threw down the gauntlet: within three years, all automobiles sold within the city limits had to meet tough smog-reducing exhaust standards. Because its deadline had passed, a 1960 burst of antismog activism converged on Sacramento to push through the California Motor Vehicle Control Act. The battle was hard-fought and intense, but the state of California thereby wound up setting pollution-fighting terms for its vast car market. (232-233)

This helps put us where we are today: when the Trump administration signals interest in eliminating national MPG standards for automakers, California leads the way in fighting back.

Ultimately, this is an interesting accommodation in the environmentalist movement. Cars are significant generators of air pollution. Additionally, cars do not just produce air pollution; they require an entire infrastructure that uses a lot of resources in its own right (building and maintaining roads, trucking, using more land for development). Yet, this passage suggests that because cars and the lifestyle that goes with them are so sacred, particularly in a region heavily dependent on mobility by individual cars, the best solution is to look for a car that pollutes less. This leaves many communities and regions in the United States waiting for a more efficient car rather than expending energy and resources toward reducing car use overall. And the problem may just keep going if self-driving cars actually lengthen commutes.
