Travel across Germany with the 49 Euro ticket
The ticket is digital-only (smartphone or smartcard), there is no paper version, and it's coupled to your personal identity (name etc.).<p>So some people have voiced concerns about that being used to profile the movement of Germany's citizens.<p>IIRC the tracking is being justified by the government "to gather statistics so we can improve the service", or something like that.<p>Disclaimer: I don't live there, I don't know the details.
