Modern Car Features, and Which Ones Are Actually Worth It

Cameras read the lane markings and either warn you or gently steer back when you drift without indicating. The evidence for lane-departure systems reducing crashes is among the strongest of any in-car technology — this is the one on the list most likely to matter.

Safety. The catch: it needs visible markings. Worn paint, snow and roadworks all defeat it, which is exactly when you most need to be paying attention yourself.

Warms you by conduction rather than heating a whole cabin of air, so it works within a minute and uses a fraction of the energy. On an electric car that difference is range you keep.

Comfort, and the best value on any options list. The catch: almost none — this is the one most owners say they would not go without again.

Starts the engine or pre-conditions the cabin before you get in, from the fob or an app. It is a genuine comfort feature in extreme climates and does nothing for you in mild ones.

Comfort, conditional. The catch: on a combustion car this idles the engine to make heat, which is fuel burnt going nowhere. On an electric car it is far more efficient and much more useful — plug in and precondition on mains power.

The boot opens and closes on a button, or on a foot swept under the bumper. Sounds like pure indulgence until you have approached a car with both arms full, which is precisely when it earns itself.

Comfort. The catch: it is slower than doing it by hand, and the kick sensor is temperamental in some cars. Try the gesture in the showroom rather than trusting the brochure.

Stitches four cameras into an overhead view of the car and its surroundings. Low-speed manoeuvring damage is the most common insurance claim there is, and this is the feature that prevents it — particularly on the tall, thick-pillared cars everyone now drives.

Safety and money. The catch: it is a low-speed tool. Lens dirt in winter blinds it, and it does not replace a shoulder check.

Fans draw air through a perforated seat, moving the humidity away from your back. Air conditioning cools the cabin; this cools you, which is a different and better experience in real heat.

Comfort, and the most underrated option on any list. The catch: ventilated is not refrigerated — it moves air rather than chilling it, and it is noticeably noisier than heating.

A second screen in front of the passenger, usually with a filter so the driver cannot see it from their angle. It is genuinely nice on a long journey with a co-pilot and completely idle the rest of the time.

Delight. The catch: it is dark whenever you drive alone, which for most owners is most of the time. Worth wanting, not worth stretching for.

A refillable atomiser in the glovebox releases scent through the ventilation, with intensity you set. Mercedes made it famous and several makers now offer a version. It is a small thing that changes how the car feels every time you open the door.

Pure delight, and honestly rather good. The catch: proprietary refills, ongoing cost, and one person's pleasant is another's headache. Try before committing if anyone in the family is sensitive to scent.

Powered mesh blinds for the rear side windows and rear screen. They cut heat and glare for passengers in the back — which in practice means children — far more effectively than tinted glass alone.

Comfort, and disproportionately useful with kids or a rear-facing seat. The catch: the rear-screen blind must retract when you select reverse, and on some cars you have to remember to lower it yourself.

The key stays in your pocket and the car starts on a button. It exists because the car already knows the key is present — the button is just the switch. On most cars you press the brake and push; on some you hold it to start accessories only.

Convenience. The catch: with no physical key turning, it is genuinely easy to walk away leaving a quiet car running — which matters most in a garage.

The car senses the fob within a metre or so and unlocks as you touch the handle. Once you have lived with it, going back to pressing a button feels archaic — it is the feature people notice most in daily use.

Convenience, with a real security note: relay attacks amplify the fob signal from inside your house to steal the car. A signal-blocking pouch at home defeats this and costs almost nothing.

One control re-maps several systems at once: throttle response, gearshift timing, steering weight, and on adaptive cars the suspension. Nothing mechanical changes — the hardware is the same, the calibration is not.

Real but modest. Eco genuinely helps consumption in traffic; sport mostly sharpens throttle response, which feels faster without being faster. Most owners settle on one mode and stay there.

A step beyond drive modes: these change how the traction control and, on all-wheel-drive cars, the torque split behave on a specific low-grip surface. Snow mode softens throttle and starts in a higher gear; mud and sand allow more wheelspin, which is the opposite of what you want on tarmac.

Genuinely useful IF you meet those surfaces. The catch: a terrain mode cannot substitute for tyres. Winter tyres on a two-wheel-drive car beat snow mode on all-season rubber, every time.

A large glass area over both rows, sometimes fixed and sometimes opening. It transforms how a cabin feels — rear passengers especially — and it is the single most effective way to make an ordinary interior feel expensive.

Delight, with real costs: weight high on the car, two to four centimetres of headroom, more load on the air conditioning, and drain channels that block. A blocked drain is how water reaches a headliner.

Your phone's interface on the car's screen — maps, music, messages, in the layout you already know. It won against built-in systems because the maps update themselves and the traffic data is better.

Close to essential now, and check it is WIRELESS. A wired-only system means plugging in every trip, which sounds trivial and is the difference between using it and not.
