Last week, I experienced a unique bus journey - by taking on-demand buses. This new type of public transportation service does not have a fixed route and timetable like traditional buses, but plans the route in real time and adjusts the direction of travel according to the needs of the passengers. As I entered the destination Central Park in my phone (?), a small blue bus drove slowly towards us. Along the way, there were only my mother and I in the bus. We looked at the scenery outside the window and soon arrived at our destination. This trip made me appreciate the convenience brought by technology to travel, and also helped me experience the warmth of the city.
