Cartoon film Cars could soon become reality with researchers revealing new software that will help vehicles communicate with each other.

Researchers have designed new software that could allow cars to 'talk'
Scientists from the University of Bologna in Italy have been working on the computer programme, which they say would allow cars to "talk" - like the red sports car Lightning McQueen in the movie - and know what was happening on the roads miles ahead.
Team leader Professor Marco Roccetti said tests have shown it could reduce crashes by 40%.
"Our app allows cars to stay in constant contact with each other," he said.
By letting cars 'talk' to each other, we can see what happens kilometres ahead - whereas current technology, instead, allows cars to perceive an obstacle only when it is physically in front of them.

"They read each other. They know the direction and speed that all the other cars are travelling, and they also know their transmitting capacity.
"All this information is updated every second or so, and the frequency is optimised so that it doesn't slow the system down."
Explaining the new technology, he said the "talking" is done via acceleration sensors built into cars that trigger an alarm message in abnormal conditions such as when a vehicle is involved in a crash.

Team member Professor Gustavo Marfia said: "By letting cars 'talk' to each other, we can see what happens kilometres ahead - whereas current technology, instead, allows cars to perceive an obstacle only when it is physically in front of them."
The new application could be integrated directly into the car dashboard or in a satnav, its researchers said in a report.
They said it will be tested on suburban streets and motorways in Los Angeles later this year before a decision is made whether to launch it on the market.-news.sky.com
