I love traveling in the UK, but we have a government and treasury that are only interested in throwing money at motorists.
The German government also usually only throw money (and quite a lot of it!) at motoring - the entire 9€-ticket thing was (in my eyes) just a move to get the massive subsidies on fuel for private cars through the greens. It's been so ill-flawed and unplanned from the start that I can not take it serious. Instead of distributing de-facto free tickets, one could have just made all public transport free for a few months - and possibly even without reimbursing existing season ticket holders. Would have saved loads of money and would actually be something to get people into public transport and not just cheapen it for those poor souls ("Alte, Arbeitslose, Asoziale") who use it already...
As things stand, nobody knows for sure on what it is valid (there are some independant bus companies in some parts of Germany which are not running on a public contract and have their own tariff - are they included? What about cross-border sections, where some domestic tickets are valid?), how to buy it (probably online, at TVMs and at ticket offices of some operators) nor how existing season ticket holders (especially those, who don't pay directly to the operator or PTE) get their money back. Two weeks to go, still just as many unanswered questions as two months ago.
Would be a shame if it did not pass the Bundesrat next week, wouldn't it?
Better to travel outside the UK anyway. Even without special deals it is better and cheaper.
Better? Try commuting in the Ruhrgebiet by public transport and then tell me that your proposition "All public transport everywhere outside of the UK is better than all public transport inside the UK" still holds without laughing. I am very certain that's impossible.
Cheaper? Perhaps, but we do pay it back in rather high taxes - and especially my generation will have to pay the stuff our current government throws out at the moment.
