ADAS (Advanced Driver Assistance Systems) are a set of systems installed in the vehicle that assist the driver to increase safety and facilitate driving, alerting to a dangerous situation and even intervening in the steering and/or brakes of the vehicle to avoid a collision or mitigate its consequences.
These systems work through cameras and sensors that collect all information from the surroundings and then act accordingly to help the driver make decisions as safely as possible.
ADAS can compensate for some human errors, but safe and responsible driving by the driver remains essential.
