Driving speeds have largely stabilized, and nowadays, safety concerns are important and reducing road accidents to minimum is a must. So, automakers are focused on safety systems more than ever before.  Given the emphasis on improving safety, it's possible that well-known phrases such as "live fast and die young" may lose their meaning as innovative   new devices are built into cars and trucks and other things that go. Many of the new safety systems that are being added to high-end vehicles are computer-assisted technologies that transfer some of the vehicle's operations to the vehicle itself, rather than relying only on the driver's decision-making skills.   For example, predictive brake assist is an in-vehicle feature that prepares the vehicle for braking when its built-in sensors detect a potential object ahead. The predictive brake assist basically places the vehicle's braking system on alert, which helps the system to slow down the car in as little time and as short a distance as possible. Other in-vehicle sensors will detect moving and still objects and will even distinguish the objects based on simple patterns, such as other vehicles vs. a person.  What's more, built-in "active systems", i.e., predictive precollision   systems, will provide drivers with advance detection of potential contact between vehicles. These systems compute the   movement of the objects and detect possible dangerous intersections  . What technological developments have enabled innovations like predictive precollision systems? Essentially, these so-called active systems are the result of vehicle-to-vehicle and vehicle-to-infrastructure communications.  These communication links allow highways to provide a vehicle's owners with services such as renting a movie during the trip, as well as reduce reaction delays when medical care is needed due to a crash.   Despite these new technologies, drivers cannot take safety for granted.  Until all vehicles are fully automated, it is the drivers themselves who are responsible for operating their vehicles and obeying traffic laws designed to keep roadways secure. So, keep your eyes on the road and your hands on the steering wheel  . Predictive Precollision can be used to   _  .
