← TechnologyWhich outcome occurs when adaptive cruise control radar malfunctions due to heavy rain?
A)Unintended acceleration from sensor lock
B)Reduced engine power from feedback loop
C)Activation of emergency braking system
D)Inaccurate following distance✓
💡 Explanation
When heavy rain obstructs radar signals, the system misinterprets reflected signals because radar function is dependent on clear sensor data, leading to an inaccurate calculation of the following distance. Therefore inaccurate following distance results, rather than unintended acceleration, reduced power, or emergency braking which rely on other failure modes.
