Vehicle peer-to-peer system

In this interesting report BBCNews tells of a vehicle peer-to-peer technology that was unveiled at CeBit in 'Vehicle warning system trialled':

Cars or bikes will pass useful information to vehicles behind them

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.
