  Talking WindScreens can prevent Accidents. urlLink BBC NEWS reports that an idea is being promoted by Dr Charles Spence, from the University of Oxford, who carried out research using a state-of-the-art driving simulator.
He claims that Hi-tech "talking windscreens" used in cars instead of mobile phones could reduce the risk of accidents. The researcher claims that that the major contribution to an increased accident risk is the distraction of a driver's attention; rather than problems with physically handling a phone. He has carried out many tests, and the drivers found it easier to divide their attention between the eye and ear if the relevant sources of information came from the same direction.
So maybe, in the near future, the mobile phones would give way to talking windscreens. However, I feel one aspect of communication that the researcher did not address is privacy of the conversation with the windscreen via media. Does everyone get to listen in on the conversation or is there a one-to-one module for this medium of communication?
