Uhm, no - when did you try travelling last? I just crossed the border to Germany from Poland(both ways) and there is nothing there. And before that I drove over in January and there was a huge queue because of "checkpoints to combat illegal immigration" and that checkpoint was just a bunch of border guards standing there looking at cars passing by, they weren't checking passports or much of anything really, it's all just theatre.
About five days ago, Szczecin → Berlin, stopped, had my documents meticulously examined and asked some typical questions I haven't been asked for a decade ("What's your proof of residence", etc).
I look like a typical WASP programmer in his forties, so no selection bias or something.
They pull out some cars, last winter I got pulled out at the border when I entered Germany from Austria. They wanted to see our passports and asked where we were going.
They wanted to see a valid national id of any shengen country, which are easier to get than passports (except in sweden, because it's the police releasing both, so might as well just get a passport).
Also did you forget flying?
