“Car dependency has a threshold effect – using a car just sometimes increases life satisfaction but if you have to drive much more than this people start reporting lower levels of happiness,” said Rababe Saadaoui, an urban planning expert at Arizona State University and lead author of the study. “Extreme car dependence comes at a cost, to the point that the downsides outweigh the benefits.”
The new research, conducted via a survey of a representative group of people across the US, analyzed people’s responses to questions about driving habits and life satisfaction and sought to find the link between the two via a statistical model that factored in other variables of general contentment, such as income, family situation, race and disability.
The results were “surprising”, Saadaoui said, and could be the result of a number of negative impacts of driving, such as the stress of continually navigating roads and traffic, the loss of physical activity from not walking anywhere, a reduced engagement with other people and the growing financial burden of owning and maintaining a vehicle.
“Some people drive a lot and feel fine with it but others feel a real burden,” she said. “The study doesn’t call for people to completely stop using cars but the solution could be in finding a balance. For many people driving isn’t a choice, so diversifying choices is important.”
