The authorities collect every year £,£££,£££,£££ in speeding tickets, parking fines, etc etc. It has become part of their budget. They actually rely on the fact that a not-insignificant part of the population will disobey the law and get fined. Why? Because that's human nature...
I had a coffee this morning with Mrs MJ at a local coffee shop. It's on a busy street corner. There's a double yellow line from the corner till the first parking bay, about three cars' length. During the 45 minutes that we were sitting there, the short stretch with the double yellow line wasn't empty for one second. Cars kept coming, parking-up, owners rushing out (presumably the age-old 'just going to the shops'), them after 10-15 minutes coming back and driving off, only for the vacant place to be immediately taken by another car. There's plenty of parking nearby, and today (Saturday) it actually free parking. But would they park legally and then walk the short distance to the shops? Of course not. Once in a while a traffic warden passes by, presumably some get a ticket, to which I imagine they will respond with a burst of expletives, cursing the traffic warden and the council. Rant over....
