Which risk increases when adaptive cruise control (ACC) misinterprets sensor noise as a leading vehicle?

💡 Explanation

When ACC misinterprets sensor noise, the phantom object causes a vehicle to use longitudinal control algorithms for following, initiating unnecessary deceleration via throttle reduction or braking because of a perceived collision risk. False deceleration, and not alternatives, results because the system prioritizes safety but incorrectly interprets environmental input.
