We have this E-Government system that centralizes almost all relations with the State, I really don’t remember when was the last time I saw an official document in paper. With all 1000+ official agencies involved, you can access and manage over 8000+ services like GDPR permissions, analogue tv frequency infos, paying traffic tickets, state-backed escrowing, fraud checks, my kids grades, my medical records etc within an handsome mobile/web app.
It was shocking to see even my German friends still need to use their physical mailboxes to handle official stuff. I can imagine it’s even worse at the rest of the western world.
Much of the UK's regular government stuff is online and very simple too - their website is actually very good. It doesn't integrate everything though. The health service is particularly fragmented and communication is often by post and not that good.
Not sure why you would think Germany is the best in this respect as I've often heard the opposite in my travels there. They are very anti-tech in government, privacy/cybersecurity reasons are what's usually cited.
