Phrase it differently.
People from different nations and different cultures may have different perceptions of acceptable road behaviour, and we should not allow 'political correctness' to get in the way of asking how great an impact such things as mass migration and the slow integration of some populations have on road safety. It is important to reach out to each and every person in every culture and sub-culture represented in the British Isles to ensure that we instil the highest possible standard of behaviour on our roads.
I'm saying, as near as dammit, the same thing.
Phrased like that, would that be racist? Would it even be contentious?
Its a bad article, thats for sure. Could have raised the same points in a more sensible and sensitive way.
