The vehicle is equipped w/ ford's driver assist package which includes blis (blind spot information system). blis only works as described 50% at best and even then is wholly inadequate and no better than not having. when blis does work, by the time the indicator triggers the vehicle triggering it was already in the blind spot. blis typically does not indicate when a vehicle is in the blind spot and tends to be triggered even when no vehicle is present. if the vehicle in/approaching the blind spot is moving fast enough (35+ mph), by the time the indicator comes on the vehicle had already come and gone; that's if the indicator was triggered at all. the indicator is also on the far end of the mirror and only a small little light which distracts the driver due to having to turn eyes/head far enough to the side to see the indicator. the main reason for the complaint is that non-driver assist package ford fusion models come standard with blind spot mirrors which allows the driver to see the blind spots without having to turn the head (turning the head while driving in traffic significantly increases the likelihood of an accident) but the driver assist package models only have blis and because of the location of the indicator the driver cannot add a third party blind spot mirror to augment the ineffective blis. blis should be in addition to the blind spot mirrors, not replace them when they do not meet the same functions and does not work as described (even when taking into account the times when ford says blis does not work). this issue has been brought to ford's attention to no avail. there have already been several times when driving that i've personally almost hit someone because the indicator was not triggered or when having to turn my head to double check while driving in traffic, both of which were not an issue with my previous non-driver assist package model. *tr
