Like tens of millions of commuters around the world, 35-year-old east London resident Jemma Taylor monitors her cycle ride to and from work.
Using the fitness tracker app Strava, Ms Taylor logs the route, speed and other data on her 7.5-mile journey to the capital’s financial centre. She uses this to set goals on her commute and for training at her local cycling club.
Her information is also being used by London’s planners. In 2016 Strava signed a contract with Transport for London, the city’s transport agency, to share its data. In October TfL renewed the relationship, signing up to a four-year contract worth $272,080.
for anyone interested in such things I would highly reccomend The Age of Surveillance Capitalism by Shoshana Zuboff. A hefty, but I think very important read
