Sounds awesome if they can pull it off. I'd love to have the interurban back in the USA. Since they already got one, this looks doable.
That aside, it would make more sense to have a monthly ticket for something between 10 to 20EUR for a region, which could be topped up for longer distances, as needed. In a simple way, to get rid of the tariff chaos.
There’s so much effort put to clean surfaces… wonder how does it compare vs air-born infections. For covid it took so long for hand cleaning mania to go away and masks to come back.
One need not be afraid to avoid unnecessary hazards.
See it the other way around: I'm still unvaxxed! So my reluctance is protecting U ;->
