What if public transit was like Uber? A small city ended its bus service to find out::Small-scale, tech-based solutions to transportation problems have emerged as a great equalizer in the battle for infrastructure dollars between big cities and rural communities.
I think 50k is definitely on the low end of what you might consider a “city”. And you’re right, it would depend on density. IMO a city with that population can’t really sustain a bus system if it’s spread out too much.
