An issue with car-to-car communication however is that the sensors can only prevent an accident with a car that’s close to them, for example if a car is 200 feet away the sensor won’t click with it and might not detect the trouble until it’s too late. Another issue is it’s quite impossible for the sensor to see past a barrier. Background: In order for car-to-car communication to work, every information that the cars announce to each other have to be processed 10 times per second by the computers installed in cars, in order for the car to correctly calculate the chance of preventing a crash. The transmitters in the cars use a steadfast percentage of wireless scale as well as a new wireless standard, 802.11 p, to validate each dispatch. Every year more than 5 million crashes occur in the U.S. and more than 30,000 of those are deadly. Car-to-car communication was created to prevent such disasters. Between 2012 and 2014, the
