Wind River OS zooms onto racetracks. I find the following part of the article interesting...
The system controls the engine and can wirelessly transmit data to pit crews monitoring the car's performance. The technology also provides a foundation for a new FIA-approved development for the 2002 racing season: Pit crews now are permitted to send electronic commands to the car to change its configuration--such as suspension response or oxygen intake.
In the Magneti Marelli device, this data exchange takes place using TCP/IP, the networking standard that underlies the Internet.
Notice how they say that pit crews are going to be able to change in car settings of the race cars wirelessly? And that they use the TCP/IP protocol to do so? I can already see it now, hackers, sitting in the stands feverishly typing away at their laptops, being paid to sabotoge a competitors car. And when it happens, remember, you read it here first!
