Questions

Hi there, here is my question:
Why would a poet vary the number of feet in lines of poetry?

Thanks!

I vaguely remember the plot of this short story that I once read in a collection of short stories by the same author. I don’t recall his name, but I seem to remember that he was a British author.
Plot: a man drives his car on a very busy urban motorway somewhere in England. He crashes over the edge and plummets down into median that is overgrown with weeds and bushes. The car disappears into this vegetation, thus nobody knows that he crashed. He is injured, broken leg, etc., so he is unable to climb out of this place. His food is whatever rubbish other passing drivers throw out their windows. He is stuck there alone, but ironically just feet away thousands of drivers pass him by. Along the way this crazy woman (who lives in some shack somewhere in this median) finds him and sort of takes him in. I can’t recall any more details.
