Lucas123 writes: Researchers are developing machine-to-machine (M2M) communication technology that allows cars to exchange data with each other, enabling vehicles to know what the cars all around them are doing, and perhaps, where they're going. Intel is working with National Taiwan University on M2M connectivity, an idea came from caravanning — an available, but-not-yet-deployed technology that uses direct line of site infrared (IR) and a range finder in order to automatically adjust the speed of cars so they can travel at a measured distance from each other. In other words, they're electronically tethered to one another. Now, imagine a group of cars traveling down the road together as an ad hoc network, each one aware of the location, any sudden actions or even the travel route of other vehicles as uploaded to the cloud from a GPS device. "We're even imagining in the future cars would be able to ask other cars, 'Hey, can I cut into your lane?' Then the other car would let you in," said Jennifer Healey, a research scientist with Intel.
