I'm fairly certain why I walk fast in a city and it's because of the lights and buses. In certain parts of downtown you turn into a video game character because you've learned how all the crosswalk lights work, how the traffic flows. So if I see that I might make a green light if I walk faster I start to speed up, and then I catch myself maybe 20 meters after the light and slow down. Same with trying to avoid bicycle paths and catch buses. It's all one big video game and it raises your pace significantly. I often catch myself walking faster than I intended and make an effort to slow down.
