That's why people carry insurance folks.
Just remember fo those who may not be aware of the UK healthcare setup.
The National Health Service delivers health care to all UK citizens free of charge at the point of delivery. This is done for the richest AND the poorest, so I would get the same treatment as Richard Branson in theory.
In fact however most of these well known people like Richard Hammond carry private health insurance with someone like BUPA, and I am quite sure that his insurance will cover the full cost of his treatment.
To say the antics on Top gear encourage boy racers to drive dangerously and cause accidents, is akin to say that reading the bible encourages people to walk on water, and this causes lots of deaths by drowning annually!
