How would you overcome the data source trust issue? In open data collection you either fingerprint the data to ensure validity or you anonymize the data to provide security, but striking the balance between the two seems like the biggest of hurdles in an effort like this.

The risk of the data being invalid seems as risky as the privacy implications in this case.

Hi, as the developer of opentrafficmap.org I can tell you that nearly all stations (traffic lights, cars, busses, trams, etc.) have a certificate, that can be validated against a trust chain managed by the EU. You can see the signature of you click "View JSON" on a tracked object

Good question. If one strong national actor (map app, for instance) could publish its live dataset, without even mixing with others, this could already be used.

Authorities could pay them for this service.
