ADAS or ADS? One letter makes all the difference!
Advanced Driver Assistance Systems (ADAS) are not the same as systems in self-driving cars (Automated Driving Systems, or ADS). What exactly is the difference, and why is it so important to use these terms carefully?
In 2024, an estimated 7,400 people were seriously injured in traffic accidents in the Netherlands, and 675 people lost their lives. These shocking figures painfully illustrate just how vulnerable road users are. Fortunately, technological advancements can make a significant difference: new vehicles are now equipped as standard with a number of driver assistance systems that can help prevent traffic accidents.
While these systems can save lives, another danger looms: confusion. Popularly, and also in the media, people often talk about 'self-driving cars' (ADS), when in reality, they're talking about cars with driver assistance systems (ADAS).
Why is this distinction so important?
1. Driver alertness – if drivers believe their car can drive completely independently, their attention decreases. Driver assistance systems (such as Lane Keep Assist or Adaptive Cruise Control) support the driving task, but never take it over. Therefore, the driver remains responsible for correctly performing the driving task at all times.
2. Preventing false security – correct terminology and communication prevents managers from overestimating systems and taking unnecessary risks.
3. Basis for future developments – a clear distinction between ADAS and ADS enables the transition from assisted driving to autonomous driving.
Let's not treat this superficially. Clear language and greater knowledge about driver assistance systems helps everyone: it prevents human suffering and lays the right foundation for the future of autonomous driving.
Call on behalf of the ADAS Alliance
The ADAS Alliance calls on media, manufacturers, policymakers and administrators to remain accurate in their use of terminology:
• Talk about 'driver assistance systems' or 'ADAS' when the driver is responsible.
• Use 'self-driving cars' or 'ADS' only for vehicles that can drive autonomously and where the driver is not responsible.
