Why is insuring US drivers on UK cars so expensive?

I've only found one company that will provide car insurance for our US friends, enabling them to drive my fully insured car in the UK. Why is this such a problem and why is it so expensive?

They aren't from the UK, or an EU country, so they're an "undefined risk". Insurers will not take their past driving history or experience into account, the same way they may have done if they were a UK or EU citizen. Try www.stuartcollins.com - they may be able to assist. It's expensive because, as I've said above, they are an unknown risk and may have never driven on our side of the road.
