According to a recent report, Mazda will be installing brake override systems on all of its models in the near future. Whenever that happens, the brake will automatically get priority over the accelerator in a situation where both of them are simultaneously depressed. Nissan already has such a system installed on most of its cars, and Toyota has already pledged to do so. As far as Japan goes that leaves companies like Honda, Mitsubishi, Subaru and Suzuki in the "Undecided" column.
A Mazda spokesman said the company wasn't aware of any unintended acceleration issues with its vehicles anywhere in the world that would necessitate such a system. This really looks to be a proactive move, since the estimated $50-per-car cost of the brake override will be much less hurtful than having to recall an untold numbers of cars... and you'll be paying for it, anyway. The company doesn't have details yet on the specifics of implementation, but it will eventually apply to every car the company sells.
