Re Roy Rodger's letter (Letters, 6 October), there is a risk of dodgy customers getting free insurance on high powered sports cars.
For example, Mr Dodgy buys an ordinary car and taxes and insures it for his accomplice and himself to drive. He loans the car to his accomplice to drive regularly. All very legitimate.
The accomplice buys a high powered sports car, not too high a value, insures it to get it taxed for a year. He lets the insurance expire, but Mr Dodgy drives it under the 'driving other cars' (DOC) extension of his own policy.
So, two cars insured, but the premium is only paid on the cheaper one. All very legitimate.
