Covent Garden to Leicester Square is a tube journey 260 metres in length and takes just four minutes to walk at street level, but six minutes on the Piccadilly line. So why do 254 people a day make the journey on the tube?This data is available thanks to the Mayor of London’s new tool, which lets you see how many people do your commute a day. It’s a nifty little time-suck, one that helps you quantify those faces you repeatedly see doing the same journey as you. With regards to Covent Garden, it’s intriguing to note that nearly 100 fewer people — 158 in total — do the journey in the opposite direction daily. Surely the people going in one direction to work must do its reverse on the way home? If anyone has any ideas as to why there’s such a large discrepancy, please let us know in the comments below.
