 (arrow):
The faster the vehicle approaches, the sooner
an indication will be displayed in the external
mirror, because the blind spot detector takes
into account the speed differential with other
vehicles. Thus even though the distance from
the other vehicle is identical, the indication
will appear sooner in some cases and later in
others.

Physical limitations inherent to the system

may not interpret the traffic situation correct-
ly. E.g. in the following situations:
● on tight bends;
● in the case of lanes with different widths;
● at the top of slopes;
● in adverse weather conditions;
