Mr. Tom O'Mahony:

I will put this in simple layman's terms and Mr. O'Malley can then give the more technical explanation. If I owned a car 30 years ago, there was no requirement to notify anybody whenever that car came to the end of its life, so the database that has been inherited has all of these old vehicles. A large number of those 2.6 million, if they were still operating, would be over 20 years old. There are all sorts of requirements and means to ensure that when a vehicle comes out of commission, it comes off the system. Unfortunately, we are stuck with millions of vehicles on this database where, apart from the fact that they have not been taxed or used to our knowledge, we cannot say categorically where they are. That is the layman's way of putting it. Perhaps Mr. O'Malley can put it in more technical terms.
