And the German government in charge of the ticket already voiced their interest in making both tickets compatible so that people can use the traffic in either country with the ticket of the other one
Could lead to a pseudo-standard that could result in an eu-wide ticket of such type in the long run
Having public transport available without having to worry about buying a ticket just because of the subscription you already have anyway is far better than interrail
This ticket is not for long distance travel but for shorter distances - it will be an extension to interrail and not a replacement
