Certainly that's a risk, but I'd hope they've done some projections on it. I'm not all that worried that this will cause overcrowding since I'd wager many people who bought the first round of tickets are just transferring over their current local subscription to the national one. Both my wife and I did that for example. It is worth noting that this ticket is 10€ cheaper than our prior subscription, which I expect will result in a solid bit less revenue for the regional transit authorities. With a system that's already straining from under-investment, hopefully this doesn't compound already existing problems.
