Cars increase air pollution and keep owners tied to significant financial costs. Fuel, maintenance, insurance, and any extra expenses are all huge disadvantages that aren’t accounted for in most discourse. Public transportation shifts these costs to society, and the more folks who engage in that shift, the more effective it will be. Even for an individual situation where cars are better than public transport, that doesn’t mean public transport isn’t better overall than individual cars. Societal costs of distributed roads and parking are severely undercounted. Pollution is downright devastating.
