I am not responsible for the dog population. It is very difficult in question and answer to discuss the merits of various restrictions upon cars in the streets, but I am certain that, while meters have some disadvantages, they have a great many advantages. They show clearly and accurately the passage of time and when a given period has expired. What is important is that they give rise to fewer offences. Paris has about 15 times the number of tickets issued in a comparable area of London—that is, 3 million a year as against 200,000. Parking meters allow for more flexible control and they have great merit. At the same time, I recognise that they have disadvantages. But on balance I think that they are the right thing for London.
