How can you spot someone who is power walking? From the comfort of your car
An officer stopping at the local donut shop encounters a man power walking across the parking lot. The officer raises his hand to stop the man. "Excuse me sir, I believe you to be under the influence of a speed-enhancing substance and I want you to complete the following test." Pointing towards a walking path that encircles a huge lake within the city's park, the officer directs the man to complete one lap around the lake and then return to this exact spot in the parking lot. The man sets off with a brisk power walking pace to complete the ordered test. The officer turns and heads into the donut shop, thinking to himself, "If he makes it back here before I can drink a cup of coffee and eat a donut, he's under arrest!"
