Washing, waxing, polishing, billing — everything that ever needed the car's fields got bolted onto it. Nobody remembers which ones mutate state, and testing <code>scrub</code> means constructing half the object graph first.</p> <p>It's the equivalent of welding the car wash onto the car: the object hauls its machinery everywhere it goes.</p> <p>But don't overcorrect — some methods <em>do</em> belong on a <code>Car</code>. <code>car.start()</code>, <code>car.lockDoors()</code>, <code>car.unlockDoors()</code> are intrinsic to what a car <em>is</em>: every car needs them forever, and they touch its own mechanical state. The absurdity isn't methods on objects — it's variable services welded into data.</p>
