The ADAS Revolution
"Why modern safety systems are changing the way we drive — and why understanding them matters more than ever."
In the rapidly evolving world of motoring, Advanced Driver Assistance Systems (ADAS) have become the silent co-pilots of modern driving—watching, guiding, even reacting when drivers don’t. But despite their increasing presence in new vehicles, a startling truth remains: many people don’t even know they’re there.
At Autotest, we’ve met customers who had no idea their vehicle was fitted with features like lane assist, autonomous emergency braking, or radar-guided cruise control. And they’re not alone. As cars become smarter, the knowledge gap between drivers and their vehicles is widening.
So, what exactly is ADAS?
ADAS refers to a suite of electronic systems in a vehicle designed to assist the driver in making safer decisions. These include technologies like forward collision warning, lane departure warning, adaptive headlights, pedestrian detection, and even traffic sign recognition. These systems rely on a complex network of cameras, radars, ultrasonic sensors, and software, all working in real-time.
When working correctly, they can prevent accidents, save lives, and make driving less stressful. But when misaligned or misunderstood, they can become unreliable—or worse, dangerous.

Why calibration matters
ADAS sensors and cameras must be precisely calibrated to ensure they operate accurately. Even a small misalignment from something as simple as a windscreen replacement, suspension work, or a wheel alignment can throw these systems off.
That’s why ADAS calibration is now one of the most important services we provide. Our workshop alone holds over 50 different calibration boards and tools, an investment we’ve built up over the past 10 years. It’s not just about having the kit—it’s about knowing how to use it, and more importantly, knowing what the systems are actually doing.
A growing concern: lack of awareness
One of the most concerning issues we’re facing isn’t with the technology—it’s with the people. Many drivers, including new ones, are handed the keys to cars loaded with ADAS features, but receive little or no guidance on how to use them. Worse still, some technicians working on these vehicles don’t fully understand the systems themselves.
That’s not a criticism—it’s a wake-up call. As a trade, we need better training, better communication, and better standards across the board. These systems aren’t just fancy extras—they’re core safety features, and they deserve the same attention as brakes or tyres.

Some vehicles have a lot more systems than others. High end, high spec Audi’s are a great example. Multiple radars, lidars, cameras and ultra sonic sensors on the front end alone.
Should ADAS be part of the MOT?
This question is gaining momentum—and rightly so. If these systems are critical to safety, why aren’t they checked during an MOT? Some countries are already exploring this. If it happens here, it could mean higher MOT costs, longer testing times, and serious implications for workshops without the proper equipment.
For garages that haven’t invested in ADAS tooling or training, this could be a real challenge. For customers, it could mean trusting only a limited number of service centres who have the right capabilities.
What does this mean for the future?
For young drivers, the future looks complex. They’re stepping into cars that are safer, yes—but also more advanced, more automated, and more reliant on systems that require regular attention and understanding. If education doesn’t catch up—through driver training, dealership handovers, or better public messaging—we risk a generation of drivers over-relying on systems they barely understand.
Where we stand
At Autotest, we’ve spent years investing in the right equipment and training to calibrate ADAS systems safely and accurately. From dynamic radar calibration to camera correction, we carry out these procedures daily and see first-hand the consequences when they’re overlooked.
The ADAS revolution isn’t coming—it’s already here. But like any revolution, it brings change, responsibility, and the need for awareness. Whether you're a driver, a technician, or just someone getting their first car—we all have a role to play in understanding this new era of motoring.
