Agreed. Which is why I submitted this in the first place. But AFAICT, it's orthogonal to GP's comment. Or not. Which is why I asked for clarification.

Transit and traffic planners would be foaming at the mouth for real commute data like this instead of just fixed point count data.

Transit fare collection systems in many metros already log tap on / tap off location data and make it accessible to planners (and police).

Google has it

AFAIK they're moving their stuff to be on device

Trust is really low that this will not be shadow-mined anyway. There’s far too much money to be made. This reads like greenwashing to me. Makes someone on the board feel good but in reality, fingerprinting and location data is still completely identifiable.
