車 I believed in driving assistance and said, "Bam!' The master of "carelessness" behind "convenience" and a six-fold increase in five years after the accident

Related traffic accidents have reached a dangerous level with the spread of adaptive cruise control (ACC), the core of advanced driver assistance systems (ADAS). According to the analysis of the "Activity of Traffic Accidents While Using Highway ACC" released by Samsung Fire & Marine Insurance's Traffic Safety Culture Research Institute, the number of ACC-related highway accidents increased from only 15 in 2020 to 101 in 2025, a record increase of 6.7 times in five years. This means that accidents are increasing rapidly at an annual average of 51.6% and it is pointed out that excessive blind faith in autonomous driving technology is leading to serious social costs.

Looking at each type of accident, the limitations of the system and the carelessness of the driver are clearly revealed. The most frequent type of accident was the "route departure type" that crashed with other vehicles or structures while leaving the lane due to road alignment or sensor recognition restrictions, accounting for 62.1% (180 cases) of the total. Following this, 18.6% (54 cases) failed to respond to vehicles that changed lanes, 14.5% (42 cases) failed to slow down while 14.5% (14 cases) failed to avoid unexpected sites such as construction sections.

Particularly noteworthy is the environment in which the accident occurred. As a result of a precise analysis of 149 cases in which black box images were secured, 77.2% of the accidents occurred in a straight section rather than a sharp curve, and 51.7% of them occurred in a situation where traffic flow was smooth. Weather conditions were also found to be "clear" at 84.6%, suggesting that the accident was concentrated at the moment when the driver had the lowest alertness, such as forward-looking negligence or drowsy driving.

Legally, ACC is only an aid at level 2 of autonomous driving, and the ultimate responsibility in the event of an accident belongs entirely to the driver. Although the road traffic law does not exempt the obligation to drive safely, there is a clear tendency for the majority of drivers to blindly trust the system. Experts stress that to prevent accidents, institutional supplementation such as mandatory monitoring devices (DMSs) that monitor the driver's condition is urgently needed as well as always preparing for intervention even during ACC use. As the carelessness that relies on convenience leads to more than 100 major accidents on highways a year, it is time to establish a driving culture that clearly recognizes the limitations of technology.
