Planning and transportation policies aim to promote wellbeing and people’s quality of life. One policy implication of our study that stems from the negative association between high levels of car dependence and life satisfaction involves promoting multimodality. One of our measures of objective car dependence (i.e., the share of car trips out of out-of-home trips) captures to some extent multimodality. The results indicate that using a car for more than 50 % of the time in a typical week, which indicates low levels of multimodality, is associated with a decrease in life satisfaction. Thus, planners and policymakers should continue to implement diverse transportation systems that integrate
alternative modes of travel such as biking, transit, ride-sharing, and micro-mobilities. Our results do not necessarily warrant the conclusion that there is a need for a complete shift away from car use; cars undoubtedly offer numerous benefits, especially given the characteristics of the U.S. transportation infrastructure and travel behaviors of American adults. Instead, our research implies the importance of travel mode diversity, which would facilitate mobility based on needs and preferences therefore reducing car dependence and mitigating its potential negative effects on life satisfaction.Land use changes are also key strategies that would help reduce car dependence and its negative externalities on wellbeing. While many travel by car because of their positive attitudes toward this mode of transportation, not all Americans drive because of a true choice or personal preference. Some are car-dependent due to land use patterns that favor car-based mobility, which may have negative implications on life satisfaction. Policies that may address this issue include compact development patterns, transit-oriented developments, car-free neighborhoods, and mixed-used urban environments.
