Poles feel collective guilt
Why would anyone feel 'collective guilt' about something as trivial as nationality? I don't feel guilty about the Ripper, and a Pole shouldn't feel guilty about drunken Polish lorry drivers.
I think there should be some tests both for British drivers entering Europe and the other way round.
For lorry drivers, yes, certainly there should be.
The difference between driving standards in Europe (for example, the low standards in Poland as evidenced by acciudent stats) is certainly a cross-border issue that needs resolving.
