Vehicles may soon be swapping information about road conditions to warn drivers about jams and dangers.
A German research project on show at hi-tech trade fair Cebit envisions a peer-to-peer
network for vehicles on a road passing data back and forth.
Cars or bikes experiencing problems would pass data that would ripple down the chain of vehicles behind them.
Information would be conveyed to drivers via a dashboard screen or through a mobile phone headset.
Dr Anselm Blocher -
a researcher at the German Research Center for Artificial Intelligence who is co-ordinating the project -
said the ad hoc communication system could mean that drivers found out about dangers or jams ahead
much more quickly than they do now. BBC News
