The radar sensor has a limited field of vision.
In some situations it may detect a vehicle
other than the one expected or not detect
any vehicle at all.

Radar sensor field of vision (grey)
Sometimes the radar sensor cannot de-
tect vehicles at close quarters, for exam-
ple a vehicle that drives in between your
car and vehicles in front.
Small vehicles, such as motorcycles, or
vehicles not driving in the centre of the
lane can remain undetected.
In bends the radar sensor may detect the
wrong vehicle or lose a detected vehicle
from view.
