Probably makes sense, since it's relatively easier for the car to be spirited off to mainland Europe and beyond.
Insurance companies are just out to make as much money as possible; in Europe their life is hard because they don't enjoy the ridiculous margins from crazy markets like US healthcare, they have to obey stricter regulation, and suffer from heavy rates of fraud in many countries.
EBay Germany has plenty of RHD cars listed from German sellers.
And what side the steering is on doesn't really matter if you're just going to chop it up for parts.
