The Swedish car manufacturer is working on a system that allow cars to share their experiences on the road eg traffic jams, slippery roads etc and so warn them (and their drivers). The data will be shared via the cloud and could also be received by emergency services and highways authorities.
“The initiative for cars to share certain information via the cloud has been announced by Volvo along with the Swedish Transportation Administration and the Norwegian Public Roads Administration. The system would use the experiences of one car that is ahead in the road and share it with other cars approaching the hazard so they are not caught by surprise. For example, cars could share information about traction in real-time and inform other cars on the road about slippery conditions.”
