People walking down the street and past an open bus.
A group of tourists hurries with their guide to catch the bus to their next landmark.
The people are not necessarily a group tourists with their guide. Walking does not indicate they are hurried. Walking past the open bus does not imply the people got on the bus, nor that they are going to their next landmark.
