The government wants make brake-throttle override systems more common in vehicles.

WASHINGTON (AP) - Federal regulators are proposing cars be required to have throttle override systems to prevent runaway acceleration in instances where the driver steps on the gas pedal and brake at the same time.

The National Highway Traffic Safety Administration said Thursday that it's proposing changing safety standards to require brake-throttle override systems in all vehicle models regardless of size, including trucks and buses. The systems automatically brake while overriding the accelerator when both are pressed.

Many car models already come equipped with such systems.

The proposal is an outgrowth of investigations two years ago into claims that mechanical defects had caused unintended acceleration in some Toyota models. Government studies rejected those claims, but the probe uncovered several cases of drivers inadvertently pressing the brake and gas pedal at the same time.
