TfL to track Tube users in stations by their MAC addresses


Even if you take out of the equation the fuzziness of detail of what goes on within a station, doesn't the fact that they won't be tracking everybody reduce the whole thing to a pointless exercise in futility?

Not only will a lot of phones have Wi-Fi switched off but it's entirely possible some people won't even have Wi-Fi enabled devices with them in the first place.
