Cute Until It Costs You: Car Add-Ons and Accessories to Avoid

We are all for a car that looks like you. We are not for the accessories that quietly make your car less safe, less legal, or lighter in the wallet for no reason. Some of the most popular add-ons out there fall into exactly that trap.

So this is the skip list. For each one, we explain why it does not earn a place in your car. And because we know some of you are going to do it anyway, we have added a harm-reduction note where one exists. Read that part as “if you absolutely will not be talked out of it, at least do this,” not as a green light. The honest recommendation is still to pass.

The Cute-But-Risky Pile (Interior)

These are the ones that hurt the most to call out, because they are adorable. They are also the ones most likely to interfere with the systems designed to keep you alive in a crash.

1. Anything dangling from your rearview mirror. Air fresheners, fuzzy dice, charms, graduation tassels, parking passes. Even a small object can block your view of a pedestrian or cyclist at exactly the wrong moment, and it is a ticketable obstruction in a number of states. The mirror is also just glued to the glass, so a heavy charm can pull it down over time. If you insist: hang nothing while the car is moving, and keep any object small, light, and removed before you drive.

2. Dashboard and dash-top decorations. Bobbleheads, figurines, and anything perched on top of your dash sits in or near the passenger airbag’s deployment path. In a crash, the airbag can launch that cute little thing into the cabin at high speed. If you insist: keep decor off the dash top entirely and choose a spot well away from any airbag cover.

3. Beaded seat cushions and bead-style massage covers. They feel nice on a long drive and they are a classic, but loose beads become projectiles in a collision and add a hard, shifting layer between you and your seat’s safety design. If you insist: skip them in the front seats and any seat with side airbags.

4. Universal seat covers that are not airbag-rated. This is the big one. Most modern cars have side airbags built into the outer edge of the front seats, designed to burst through a special tear-away seam. A cover that wraps over that seam can delay or misdirect the airbag. The NHTSA has documented that aftermarket items in the deployment path can interfere with how an airbag works. If you insist: only buy covers explicitly labeled side-airbag compatible or SRS-safe for your exact make and model, and have them installed correctly.

5. Steering wheel phone or tablet mounts. Mounting a screen on the wheel puts a hard object directly in front of the driver’s airbag and right in your sightline. If the airbag fires, your phone becomes the first thing your face meets. If you insist: never, and we mean never, on the wheel. Use a vent or dash mount placed low and to the side instead.

6. Loose or overly fuzzy steering wheel covers. A cover that does not fit snugly, or one so plush your hands slip, costs you grip and control in the exact moment you need it most. If you insist: buy one sized to your wheel’s diameter with a non-slip underside, and replace it the moment it starts to slide.

7. Steering wheel spinner knobs. The “suicide knob” nickname is not a marketing term. For most drivers they are a control hazard and are restricted in some places. If you insist: this one is a genuine no from us unless you have a medical need and a properly fitted adaptive device prescribed for your situation.

The Ticket Magnets (Legal Trouble)

Looks great in the driveway, gets you pulled over on the road.

8. Tint darker than your state’s legal limit. Dark front-window and windshield tint reduces how well you see out at night, when visibility already drops, and it is regulated by visible-light-transmission limits that vary by state. Too dark means fines, failed inspections, and a real night-driving hazard. If you insist: stay within your state’s legal VLT, keep the windshield clear, and consider a near-clear ceramic film that blocks heat and UV without darkening.

9. Aftermarket LED or HID “conversion” kits in halogen housings. Dropping LED or HID bulbs into a housing built for halogen scatters the beam and blinds oncoming drivers, even when the bulb itself is bright. Federal Motor Vehicle Safety Standard 108 makes most of these conversions non-compliant for road use, which is why so many are sold “for off-road use only.” If you insist: only install a complete, DOT-approved headlight assembly designed as a unit, and have the aim checked.

10. Underglow, colored exterior lights, and busy interior LEDs while moving. Color and flashing-light rules vary by state, and bright cabin lighting is a distraction and a glare source while you drive. If you insist: keep underglow and color displays for parked shows only, and set interior lighting to dim or off whenever the car is in motion.

11. License plate covers, tinted frames, and “photo blocker” sprays. Anything that obscures your plate is illegal in many states, and the sprays that promise to defeat traffic cameras largely do not work. You pay money to risk a ticket. If you insist: there is no safe version of obscuring your plate. Leave it clearly visible.

12. Radar and laser jammers. Active jammers are illegal under federal law, full stop. (Radar detectors are a separate thing and are restricted in some states and banned in commercial vehicles, so check before assuming.) If you insist: skip jammers entirely and just drive the limit.

13. Aftermarket air horns and train horns. Fun for exactly one prank, then it is a noise-ordinance violation and a startle hazard to other drivers. If you insist: keep the factory horn.

The Money Pit (Waste and Scams)

These will not hurt you. They will just take your money.

14. Magnetic or plug-in “fuel saver” devices. The little gadgets that clamp to your fuel line or plug into your OBD port and promise huge mileage gains do not work. The FTC has taken action against sellers of magnetic fuel-saver devices for false claims, and the EPA has tested scores of these gadgets with essentially nothing to show. If you insist: do not. Real savings come from proper tire pressure, smooth driving, and following your maintenance schedule, all free.

15. Cheap no-name USB chargers and fast chargers. Bargain-bin chargers with no recognizable brand or safety certification can overheat or damage your phone. The few dollars saved are not worth a melted port or worse. If you insist: choose a charger from a reputable brand with proper safety certification.

16. Novelty metal pedal covers. Shiny aluminum pedal pads can get slick, especially with wet shoes, and a slipping foot on the brake is the whole ballgame. If you insist: choose pedal covers with a genuine rubber grip surface, not bare metal.

17. Tire shine applied to the tread. Glossy tire dressing belongs on the sidewall only. Get it on the tread, or let it sling onto your brakes, and you have made the parts that stop you slippery. If you insist: apply carefully to the sidewall, wipe any overspray, and keep it off the contact surface.

A couple of things are not on the skip list, but get used wrong constantly.

18. The folding sun shade. Great for parking in summer. A crash hazard if you ever pull away with it still up. Always stow it before you move.

19. The phone ring or pop grip as a driving mount. A pop-socket is for holding your phone in your hand, not for propping it while you drive. Use a real mount and keep the phone out of your lap.

The Short Version

If an accessory blocks your view, sits in front of an airbag, makes you harder to see out of or other drivers harder to see, or promises results that sound too good to be true, it is not worth it no matter how cute. A car that looks like you and keeps you safe is the actual goal. Everything on this list fails at least one half of that.
