Quoting: Another One
If anything, during the last 70-80 years their society taught them to be irresponsible.
So do you suggest that Poland was communist before WW2? A very novel point of view, if I may say so.
As for Polish driving and Polish drink-driving: road accidents happen a lot in Poland because of the many narrow, potholed roads still around, and because a lot of country dwellers insist on walking / cycling down motorways dressed in black, gray, and other dark colours just as dusk is falling. I have personally missed a few by virtually centimeters. It's no fun! Plus, as in every country, young people get high on alcohol and drugs, and then proceed to drive their friends home from night clubs or parties.
Polish drink-driving in the UK: as someone mentioned above, when you go abroad, you don't really feel that this new country is "for real" - because your home country is the only real one, right? You would especially tend to feel this way if your education wasn't the greatest, and let's face it - lots of immigrants come from a working-class background. Thus, you tend to disregard the rules, firstly because they are written in a language you don't bother to understand, and secondly because you are "abroad" - i.e., in never-never land. You came here for the freedom of not being recognized, for the money and the irresponsibility (as opposed to being a REAL citizen back home). I think this attitude is sh*t but I know quite a lot of people who actually feel this way.
On the other hand, this is not a typically Polish thing, as most people tend to fall for this fallacy (like the British chav who gratified himself in a public fountain in Bratislava some time ago - no way he'd have done that in his home town, or at least I hope so). Generally speaking, unless you are a seasoned and sensitive traveller, living abroad will always be associated with having
less overall responsibility, not more.
