Why You Should Not Trust Your Car’s Automatic Systems Completely

Most modern drivers assume that if a feature is labelled “automatic”, it will take care of itself. Automatic lights. Automatic braking. Automatic lane correction. The car feels intelligent, almost watchful.

But there is a quiet issue that many drivers are unaware of, and it begins with something as simple as headlights.

The automatic headlight problem

In fog, heavy rain or dull grey daylight, many cars will show illuminated front lights but leave the rear of the vehicle dark. From inside the car, everything appears normal. The dashboard is lit. The automatic light symbol is active. You can see light reflecting ahead.

However, what often happens is that the vehicle is running on daytime running lights rather than full dipped headlights. On many cars, daytime running lights only operate at the front. The rear lights remain off unless the dipped headlights are manually switched on.

The system relies on a light sensor that measures brightness, not visibility. Fog does not always make the environment dark enough to trigger full headlights. Heavy motorway spray can reduce visibility dramatically while still registering as daylight. The result is a vehicle that is difficult to see from behind, especially at speed.

Under the Highway Code, drivers must use headlights when visibility is seriously reduced. Automatic systems do not override that responsibility. In poor weather, manual control is often the safer choice. It is a small action that can make a significant difference.

Automatic emergency braking is not foolproof

Automatic Emergency Braking, often referred to as AEB, is one of the most widely praised safety technologies in modern vehicles. It is designed to detect obstacles and apply the brakes if a collision appears imminent.

In controlled testing, it reduces certain types of crashes. But it is not infallible. Cameras and radar can struggle in heavy rain, low sun glare, fog, or when sensors are obstructed by dirt or ice. Some systems have difficulty detecting stationary vehicles at high speed. Others may not recognise pedestrians at certain angles.

It is a safety net, not a guarantee.

Lane assist is not autopilot

Lane keeping systems gently steer the car back into its lane if it detects a drift. On clear motorways with bright road markings, they can work well.

On rural roads, in roadworks, or where markings are faded, they can disengage or behave unpredictably. Drivers may not even realise when the system has switched off. Over time, there is a risk that drivers become less attentive, assuming the vehicle will correct mistakes.

It will not.

Cars drive on a wet highway during sunset. The sky is golden, and trees line the road. The scene is viewed through a windshield.

Adaptive cruise control still requires full attention

Adaptive cruise control maintains speed and distance from the car ahead. It is comfortable on long motorway journeys.

However, it does not anticipate hazards like a human driver. It can brake sharply when another vehicle exits your lane. It may not react appropriately to a fast vehicle cutting in. Most importantly, it does not read the wider context of traffic conditions.

It reduces workload, but it does not remove responsibility.

Blind spot monitoring is not perfect

Blind spot indicators are helpful, especially in heavy traffic. They provide an extra warning when another vehicle is alongside you.

But motorcycles, fast approaching cars, or vehicles at unusual angles can sometimes escape detection. Sensors can also be affected by weather or dirt. A physical shoulder check remains essential.

Cameras distort reality

Reversing cameras and parking sensors have reduced low-speed bumps and scrapes. They are undeniably useful.

Yet cameras distort depth perception, and small or low obstacles can be difficult to judge accurately. Relying entirely on the screen rather than physically checking surroundings is one of the most common causes of minor accidents.

The bigger risk is complacency

There is a growing concern among safety researchers about automation complacency. When systems work well most of the time, drivers begin to relax. Attention drifts. Reaction times lengthen.

Modern vehicles are safer than ever, but the technology is designed to support an attentive driver. It is not designed to replace one.

The word “assist” appears frequently in the naming of these systems for a reason. They assist. They do not assume control.

Automatic lights, braking, steering correction and cruise systems are impressive pieces of engineering. They reduce risk. They improve comfort. But they still require a human driver who understands their limits.

Trusting technology is reasonable. Trusting it completely is not.

Netflix’s Sex Education Season 4 Might Be Its Most Important Season Yet

Season 4 of the popular comedy-drama 'Sex Education' is out. It's a show I love, mostly due to just how relatable it is. While previous seasons have explored the trials and tribulations of puberty in high school, this season tackles the challenges of college students.

It's a weird time when you're 17. You're given much more independence than before, and you have the chance to learn to drive a car, yet you're not an adult yet. It's a time when you are truly starting to understand who you are. The show doesn't hide this at all. There are people going through all different kinds of identity understanding, whether that's who they are sexually attracted to or what gender they believe they are. This will be quite jarring for some viewers. This season is very 'woke,' but that's been done on purpose. While the show isn't literal sex education, it is produced in a way where you're supposed to learn from the characters and apply it to your own life.

Having nearly no straight characters in college won't be everyone's cup of tea, but this isn't trying to be a realistic portrayal of college. The point is to learn and understand more about gender beliefs by showing the many different forms they come in. The season particularly focused on people who have transitioned sexes or are still in that transitioning phase. For example, I had no idea of the aftereffects of taking testosterone for the first time or how hard and expensive it is to have top surgery. More and more people are questioning their own identities; it's not something that is going to go away, so no matter what your opinion, it's important to at least try to understand how difficult it can be for people.

Perhaps my favourite part of the season surrounds Jackson Marchetti. His character has lesbian parents. While he has always been a big part of the show, they've never really delved deeper into what having gay parents can be like. In the show, he discovers a lump on his testes. When he goes to the doctor, he's asked questions about his family history and if there's any illness that runs through the family. This makes him start to question where he comes from and who his biological father is. I personally went through the same thing. I have lesbian parents and also started to question who my biological father was after finding a lump. He's unsure what to say to his moms. You don't want to upset them, obviously, but he also wants answers on who he is and where he comes from.

While Jackson's part was very interesting, the show didn't go as deep as I would've liked them to. In the show, it turns out he isn't a child of IVF treatment, but instead, his biological mother was having an affair, and that's how she fell pregnant with Jackson. For me, this is incredibly lazy from the producers. They didn't truly explore how children can find their biological father. There are charities that will help you to find your father, but there is one big issue with this. If you were born in 2001 or before, you cannot find your father. Back then, donors were protected by law, meaning their identity must be kept a secret. All I will ever know about my sperm donor is that he was a university student studying maths at Manchester. That's it, and the law won't change that. I personally have come to terms with this and don't really care about it, but for a show targeted at teenagers, I think they would've caused someone in my position more issues than answers.

This season is meant to be the last of the show and, in truth, is a great way to end it. I'm not sure what else they could really do to continue the series without it starting to feel stale. Most of the issues the characters faced have now been resolved or brought to a stage where there aren't any glaring questions that need answering. You can keep your Breaking Bad; Sex Education is Netflix's greatest show.
