The not-too-distant future of driving: When cars can talk, crashes may be avoided

Within a few years, cars whizzing down the highway will begin chatting among themselves. Once they all are equipped to join the conversation, every car will know the speed, distance and direction of every other car close enough to pose a risk. Are cars slowing abruptly just beyond that tractor-trailer you can’t see around? You may get an alert, but if there’s no time for discussion, you may just feel your brakes squeeze on. A speeding pickup truck seems likely to run the red light as you approach the intersection? Your car may decide to stop rather than put you in danger. Just as it has changed so many other aspects of life, wireless technology is about to revolutionize the way we drive.
