However before making assumptions, remember that Assumption is the mother and father of all f**k ups, it is important to go back to the documents that preceded to cancellation of MOT's for 40+ year old vehicles. Since the introduction of the computerised recording of MOT tests it became very easy to analyse the results by, total age, specific year, vehicle type etc. Well done the computer boys for once.
The House of Commons Committee did just such an analysis and found exactly what WE would/should have expected.
a. Failure rate for all reasons on vehicles over 40 years old was less that 1%, as I recall.
b. Questioning MOT test centres it became clear that owners of such vehicles were in fact keeping their vehicles it outstanding mechanical condition.
c. Vehicles of the relevant age were doing generally doing less that the average annual mileage of some 12,000 miles per annum. Indeed , as I recall it was in the order of sub-3000 miles per annum.
d. This I find significant and interesting. It was established that whilst moder mechanics were able to do the test on a modern vehicle they mostly had no idea what to look for on Historic vehicles.
e. As vehicles are becoming more technically advanced the standards have become impossible to enforce on old vehicles. Examples given were noise and exhaust emissions.
f. The 40+ year old vehicles had a great safety record as very few were ever involved in accidents due to both low mileage and driver/rider care when on the road.
So they applied perfect logic, for once, when they changed the rules. Remember that they did caveat the change with the driver responsibility to keep the vehicle in roadworthy condition at all times.
