Just for info; in Norway all vehicles (cars and motorcycles) older than 30 years are exempt from inspection. This rule has been in place since tri-annual inspections were introduced years and years ago. Research confirms that such vehicles only very rarely are involved in accidents, and when accidents do happen they are not caused by the condition of the vehicle as such. In the few instances where the rider/driver of the old vehicle is to blame, the cause of the accident is mostly that the vehicle is driven recklessly in relation to its abilities (brakes, cornering, speed etc), or that the general traffic rules and regulations have been breached. One may perhaps assume that the same will be true in other reasonably civilised countries?
