Understanding Side Collision Avoidance Systems' Limits

Modern vehicles are increasingly equipped with Side Collision Avoidance (SCA) systems, a suite of technologies marketed under names like Blind Spot Monitoring (BSM) and Cross-Traffic Alert (CTA). These systems promise a significant safety boost, using radar or ultrasonic sensors to watch where the driver cannot. However, a dangerous gap exists between marketing promises and technical reality, leading to widespread over-reliance. A clear-eyed look at the fundamental limitations of these systems is essential for using them safely rather than being lulled into a false sense of security.
