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.

Aston Martin's City Car Chronicles: Decoding the Unlikely Tale of the Cygnet

When you think of Aston Martin you think of iconic British sports cars. Cars that are so good even James Bond had one, so why did the company release a small city car called the Cygnet?

Back in 2009, the European Union were creating new legislation to reduce CO2 emissions. The new rules meant companies had to comply with an average CO2 emissions goal across the entire range. For my companies this was fine but those who only made sports cars would find this more of a challenge. Luckily for a lot of sports car companies, they were owned by a sister company that would bring this average down. Lamborghini for example is owned by the VW group so they didn’t have to worry. Aston Martin on the other hand wasn’t owned by a company that produced your average daily commuter.

At first, Aston Martin tried to push back against the European Union’s new legislation. They believed the EU should be judging a car based on the amount of CO2 it emits over its entire life. Aston Martins on average were only driven 6000 miles per year, significantly less than other cars, meaning it would add less toxins to the environment. The EU didn’t agree and the legislation was here to stay. Aston Martin had two options, become a part of a larger motor group so the average CO2 emissions from the entire range of the manufacturer could be applied or add a car to their range that had very low emissions. Not wanting to “sell out”, Aston Martin chose the latter and would create a new car to bring their range’s average emissions down.

Except they didn’t create a “new” car. Instead, they had an ingenious plan. They would take a highly efficient, low-emissions car from another manufacturer and modify it for themselves. This happens all over the automotive market. Cars will be sold under different badge names to suit a certain market. All Aston Martin needed was a friendly company willing to strike a deal, one that wasn’t competing in the same market space as themselves.

Toyota were just announcing their new city car, the iQ. This was a tiny city car that was easy to park and, crucially, low on emissions. For size reference think of anything like a Fiat 500 or VW Up! . The iQ looked like the perfect option for Aston Martin so the companies got together and struck a deal. Aston's design team were no longer creating a brash sports car, they were modifying an upmarket Toyota iQ. It would be called the Cygnet, named after a baby swan about the “swan doors” found on Aston Martins.

The Cygnet would be marketed as a “tender for your yacht”. They imagined most owners would be the car to take them from their Mayfair residence to their garage where they’d swap the Cygnet for a much more powerful Aston Martin to continue the rest of their journey. That’s a pretty small market to target but the point of the car was to bring those average CO2 emissions down. At first, you had to already be an Aston Martin customer just to order the car.

The outside of the car unsurprisingly looked like a Toyota iQ. The front end was slightly redesigned to feature the iconic Aston Martin grille, whilst at the rear new Aston Martin styled lights were added alongside a small spoiler. The door handles would be replaced by more upmarket ones that sat flush with the car’s body. This was not only more aesthetically pleasing but also made the car more aerodynamic. Even with these changes, this didn’t feel like an Aston Martin.

In regards to the interior, the designers tried their best to make this car feel like a proper Aston. There was plenty of leather placed all over the cabin where cheap plastic would be on the Toyota iQ but things like the buttons and switches were still obviously that of the Toyota.

Production would begin in 2010. The car would start its life in Toyota’s factory in Japan before being sent over to Aston Martins factory in the UK. A basic white or black iQ would be sent over and then stripped down so Aston Martin could apply its paint to the standards it expected. Just the paint would take 50 hours. The previously mentioned flush door handles were dropped in favour of the original ones from Toyota. Each car would take 175 hours to create as opposed to the around 10 hours Toyota would take.

All these labour hours might explain why the Cygnet was 3 times the price of the iQ at over £30,000. The market wasn’t there for the Cygnet, a luxury city car wasn’t needed. The closest competition came from the Audi A1 but this was less of a city car and more just a small one. By 2013 Aston would pull the plug on the Cygnet after only selling 800 cars. The EU legislation changed and the rise of the plug-in hybrid meant Aston Martin did not need this future icon any more.
