Acura, for example, made a big advertising buy during the recent NCAA basketball tournament to tout its backup sensors, which apply the brakes automatically to avert danger. It is among several automobile manufacturers that are using infrared distance sensors, radar and cameras to provide warnings about safe distances and when other vehicles are sliding dangerously into your lane.
Those and similar advancements that preceded V2V are expected to significantly reduce accidents, which the Insurance Information Institute said cost more than $1 billion in claims in 2010. The Insurance Institute for Highway Safety estimated that if all passenger vehicles were equipped with forward collision warning, lane departure warning, side-view assist and adaptive headlights, which respond to the direction and speed of the vehicle, about a third of fatal crashes and 20 percent of those that result in injury could be prevented or mitigated.
The current generation of devices also may be integrated into V2V systems as they begin to find their way to the dashboard.
