Cars are so packed full of computers these days, it's a surprise that they haven't already been programmed to talk to each other to avoid idiot drivers driving them off the road. Well, it turns out the technology exists, and South Australia is trialling the technology for three months.
Created by Aussie company Cohda Wireless, each of the 100 cars in the trial is fitted with a small box that uses GPS and Wi-Fi signals to determine a car's proximity to other vehicles, and raises an audio alert when the car starts getting a little too familiar with its roadside companions.
If all goes well, we could apparently be seeing the technology in cars by 2015. Of course, it won't completely eradicate road fatalities, but if it helps avoid any type of accident (which it surely will), then it will totally be worth it.
