Back in 2008, Continental AG introduced its Accelerator Force Feedback Pedal
as a safety device. The idea was that sensors in the car would know when the vehicle was getting into dangerous situations, and the pedal would then vibrate a little to warn the driver to take action. At the time, there was talk about the pedal also being useful to save fuel by vibrating when the driver was accelerating too hard. Conti is now studying the green aspect of the AFFP
a little more seriously.

reports that Continetal's chassis components business unit executive vice president, Peter Laier, said internal studies have found that using the vibrating pedal as a way to signal the right time to change gears can cut carbon dioxide emissions by about 5 to 10 percent. Sounds like an easy-to-implement, if somewhat annoying, fix. Laier said we might see the fuel-saving pedal reach a production car in 2012 or 2013.
