Supporting detail 1: One advantage of public transportation is people don’t get stressed driving. They can relax, read a book and work on a crossword puzzle.

Do I need to add more sentences for the part above I need at least 3 or 4 sentences?

Can you think of another sentence I could add for the supporting detail 1 above?

This is what I've got so far "Supporting detail 1: One advantage of public transportation is people don’t get stressed driving. They can relax, read a book and work on a crossword puzzle." The part I have written so far must stay because the teacher gave me an example.?
