I first thought it'd be like those electric scooter hire, or maybe bike hire schemes.

But looking on line it looks like it might be just a city run version of uber.

I used to live in a rural county that had regular bus routes which worked as one would expect and shorter busses you could schedule for a window the day prior or earlier. They would figure out allocation ahead of time show up and pick up and drop off a bunch of folks and drive everywhere in the boondocks.

This served as a connection between areas too rural to be Worth serving with regular routes and the more traveled parts.
