As federal regulators consider making brake override systems mandatory on all vehicles, General Motors is taking the initiative to install the system in all its new vehicles world wide by 2012.

GM has not had major problems with unintended acceleration, but the company said it was taking the step as a means of reassuring customers about the safety of its vehicles. GM plans to install the software for the system in the electronic throttle control systems of newly manufactured vehicles. The automaker already used it in several models in the United States, mostly high horsepower vehicles like the Chevy Corvette.
