There are plenty of legal immigrants who are used to driving on the other side of the road, but even so the rule is easily understood - you give way to traffic on the roundabout. I don't think there are even any places left in France with their daft old rule about giving way to the right even though they drive on the right.
And many illegal immigrants have probably never driven before.
What point are you trying to make?
