Most analyses of car dependency focus on direct costs such car payments, insurance, gas, and infrastructure. However, CityNerd, a transportation planner turned YouTuber, examines the broader societal cost of cars including direct expenses and externalities like pollution, greenhouse gas emissions, land use infrastructure, and health impacts. Using data from a 2018 European Union study, CityNerd compares the net societal cost per mile of cars with other modes, such as bicycling and walking. The study finds that society incurs $1.47 in external costs per car mile, compared to $0.19 per mile for walking and a $0.05 net benefit for bicycling. In the U.S., where drivers cover 3.2 trillion miles annually, this equates to nearly $5 trillion in societal costs each year.
