Chess and the No Claims Bonus

Here is another idea for the psychologist to research.
If you play chess regularly you get a grade, a number, and this number accurately reflects your playing abilities – unfortunately.
I saw a TV program years ago about good driving. It was proposed that good drivers recognise changing patterns in the road as they drive – bad drivers dont. Seemed plausible to me.
Back to chess – a good chess player is one who above all else recognises changing patterns in the game. A good chess player contrary to popular notion is not primarily a good calculator.
Given those two pieces of information it occurs to me that a good chess player should be a better motor insurance risk than a bad chess player. The chess grading system puts a number to, quantifies, the players ability and if the idea holds the chess grade should correlate with the driving ability.
To test the theory would be simple and would cost hardly anything – comparing chess grades and claims records. It would also be a cheap piece of publicity for the insurance company doing the research as it is just the kind of thing the press love.
