There are those who don't like fancy ornamental wheel covers, and they reserve special detestation for spinners. There are even some jurisdictions that claim they constitute some sort of safety hazard and therefore seek to ban them. What nonsense! I think that the impulse to install them is very much akin to the one that leads kids to thread crepe paper through the spokes of their bicycles and to attach baseball cards with clothespins to make a noise when the spokes pass the card. The cheapest wheel covers are held in place with springs and bounce out sometimes when the vehicle to which they're attached hits a rough spot wrong. Are squirrel tails on the handlebars very different from welded chain-link surrounds for license plates or even made into a substitute for a steering wheel? There are spinners for trucks and also, of course, for bikes. People usually return to retrieve their bounced-out covers, but the one completely abandoned graces our gate and is very ornamental there, too.
