> It allows you be tracked via your card, and if you look at this with an dystopian viewpoint could enable you to become targeted by specific advertising based on your purchases while riding the escalators for example
Transport for London already do much deeper tracking than that based on WiFi. They know how many people use the stairs vs the escalator, which areas of the station become congested fastest during peak. It's helped them redesign stations for the better. I'm fine with that, I can opt out by turning WiFi off.
TFL is run by the Mayor, so if dystopian microlocation-based advertising was even proposed I would expect it to end very badly for him in a political sense.
