Insurance scam by eastern european drivers

My car is on Polish plates and is insured at all times however long it is out the country, it was the same when i lived in Denmark, I would have thought the Uk would have a way of making it difficult or different. Orys is correct, after 6 months of living in Denmark I had to register by RHD car to Danish plates, so in that respect its not possible to have a car full time in another EU country not on local plates, but insurance is not the problem. I pay “road fund” tax when i fill up in Poland, not a yearly paid tax, so when I am in the UK its all free.
