Motorists could be driving so-called “smart cars,” that use sophisticated technology to communicate accident hazards to other cars in the environment, much earlier than earlier believed.
The National Highway Traffic Safety Administration recently announced that it is closely studying the possibility of requiring such crash avoidance systems that communicate with systems in other cars, on all light vehicles. According to the National Highway Traffic Safety Administration, it is considering requiring all light vehicles to make use of technologies that enable them to communicate with each other using electronic systems. The data that will be shared between vehicles would include important information like speed and location to help vehicles make appropriate changes to driving processes to avoid accidents.
The term “crash avoidance technologies” is used to refer to a vast body of technology that is mainly targeted at helping identify accident hazards in the environment, and mitigating the risk of accidents. Such technologies have been used in commercial vehicles for several years now, but these technologies are stand-alone technologies, and currently do not involve communication with other vehicles in the environment.
However, vehicle-to-vehicle technology would include communication with other vehicles within a certain radius to share information that could help prevent accidents. In fact, many safety experts believe that this technology is the future of auto safety, and could help prevent several lives in car accidents every year.
Obviously, this technology would not be able to prevent the kind of accidents that occur as a result of driver error. For instance, the technology may not be able to help prevent accidents caused by a driver under the influence of alcohol. They may be able to help prevent other serious accidents like the often-fatal accidents that occur as a result of red light violations.
