WE’VE BEEN ASKING THE WRONG QUESTION.
Our research tells us that lots of problems stem from the way we use cars. We price roads wrong, so people overuse them. Cars are a major source of air pollution, including carbon emissions. Car crashes kill tens of thousands of Americans every year, injure many more, and cost us billions in medical costs and property damage. And building our cities to accommodate cars leads to a suburban development pattern that pushes us further apart from one another, creating infrastructure costs that drown our cities in massive maintenance expenses.
