I mean, if I were to wait for my own country to digitalize anything of its complex and complicated bureaucracy, then I could wait a thousand years. Now there are so many issues where you have to go in person, from one place to another, to fill documents and so on.
I wished EU could come up with some nice customizable internationalized web sites and applications, so that it would make it seamless for member states to change to that.
Also, it would be nice if we had EU mobile applications for traveling – kind of like goeuro.com, but to find trams, metros, buses, taxi stations, etc. no matter what EU city you are currently in.
