I hate to tell you, but not all German trains are high-speed links; the vast majority of them are old, slow and smell of ****, just like ours. Their trains run on time, same as the Swiss trains do, because they allow an additional 10 minutes for each journey, not because of any fantastic leaps forward in technology or hardwork.
Autobahns are excellent, when they are not being dug up. Honestly, I had to put up with years of roadworks around Stuttgart, and same as the UK they never seemed to be anyone working on them and they never made progress.
As for cleaner, that's not really my impression. People over there still litter and graffiti is rife. I lived there for some time and I still spend a lot of time over there on a regular basis. I loved my time there, but it's not some amazing paragon of what we should all aspire to; it's a modern European country, like France or the UK. It's better in some regards, and worse in others.
