While your story is an entertaining one, I disagree with the conclusion that your experience is proof of the usefulness of geometry in everyday life. Your anecdote is based on the assumption that you were able to accurately estimate the length of the crosswalks, which is a subjective measurement. Additionally, the Pythagorean theorem only applies when the right triangle is a perfect square, which is an unlikely scenario in a real-world situation. Therefore, it is not possible to accurately calculate the proportion of steps you saved by jaywalking. You are wrong in claiming that your experience is proof of the usefulness of geometry in everyday life.
