“The system” being the British road network.

There are incorrectly issued PCNs, but the majority are correctly issued. Out on the streets, I see so many examples of stupid, thoughtless and dangerous parking that the concept of enforcement ceasing fills me with dread. I’ve seen streets blocked with people stopping in the middle of the road, blocking off busy bus routes, to chat. I’ve seen people sat across junctions seemingly genuinely confused about why I want them to move. I’ve seen vehicles parked blocking the view of pedestrian crossings, endangering pedestrian lives. I see a lot of people parked just around blind bends, endagering their own vehicles.

The vast majority of PCN issued are issued because the person that paked the vehicle is too lazy to walk an extra 10 feet, too stupid to read the sign, or too arrogant to realise that they may be caught.
