Most people use the M25 like a sadistic shortcut. You’ll hear, “Just take the M25, it’ll save you time,” and then you’re stuck near junction 10 for two hours watching a hawk eat a pigeon. That 117 miles is a promise that the highway code breaks.
Did you know the M25’s circumference is almost exactly the same as the distance from London to Paris? Yes, you could drive from Big Ben to the Eiffel Tower and back with 20 miles to spare. Instead, you’re using that same distance to orbit a retail park in Thurrock. Priorities, people.
The Fuel Economy Horror
Let’s talk petrol. If you drive a Ford Fiesta, a full lap of the M25 will cost you about £20 in fuel. That’s a nice dinner, wasted on idling behind a Nissan Micra. But here’s the kicker: if you had a perfect smooth run (impossible), you’d use just over 6 gallons of fuel. In stop-start traffic, you’ll burn through twice that, plus your will to live.
I once met a man who claimed to have done the “full loop” on a Sunday morning. He said it took three hours, and he had to stop for coffee twice. He was treated like a mythical hero, like someone who’d wrestled a swan. The truth is, the M25 is a state of mind, not a stretch of tarmac.
