Thanks K but this is too serious. I am thinking more along the lines of the American punter who bought a Winabego with all the gear including the cruise control. He took it on holiday and on a stretech of road put it into cruise control and went in to the back to make a coffee. The Winnie immediately crashed and he successfully sued the dealer as the salesman did not tell him that when cruise control is selected you must remain in the driving seat to control the vehicle.
Thats the sort of story which makes my day.
Ever noticed why, when you buy a car from a dealer, they show you bits on the car which are every day things such as indicators, wipers, horn, lights etc.
Makes you think that this is the first time they think you have ever driven a car.
