Make an argument for making buses free to ride in cities.


assistant
Making buses free to ride would increase ridership. This benefits cities by reducing cars on the road, reducing traffic congestion and pollution. People who rely on buses often have lower income, and not charging bus fare would be disproportionately beneficial to them. Not charging a fare also avoids the need to maintain payment infrastructure on buses.
