Can someone explain to me how this is helpful or necessary? AFAIK the speedometer is the most prominent element in the instrument cluster of most motor vehicles (save some like the traditional Porsche 911 cluster arrangement). If you are behind the wheel and don’t have at least a rough idea of how fast your vehicle is moving and the applicable speed limit, you may already be more distracted than you should be. How does flashing something on the entertainment display (not directly in front of driver in most vehicles) make things better?
Some modern vehicles already have this function built-in but at least in that case, the warning appears in the instrument cluster and/or HUD (if the vehicle has one), which I would expect the driver to be checking regularly.
