Volvo's Blind Spot Information System (BLIS) lends itself to unsafe conditions. This is true for the many drivers who are used to driving cars that are smilarly equipped. For nearly 15 years I have been driving cars that were similarly equipped and when activating the turn signal in the direction where the system indicated another vehicle in the "blind spot" an audible warning sounded until the turn signal was extinguished or the danger passed. Volvo fails to provide the audible signal and thus, if there is a failed LED in the mirror, there is no indication of a vehicle in the blind spot and no redundancy. Further, habits are hard to break and after driving cars with the audible warning, and relying on it, it is difficult to get used to not having it. In addition, all the cars that I personally drove with HUD (head up dispay), vehicles in the blind spots were displayed on the HUD. Volvo cars are equipped in terms of hardware to enable these functions (audible warning & HUD display) with simple software patches. One additionl point, the lights on the mirrors can be practically invisible during the day with sunlight behind the car and at night with bright lights illuminating the mirrors from behind. I feel it is imperative that Volvo is compelled to incorporate the proposed changes as those would certainly mitigate potenial accidents.
