This has got to be the strangest idea we’ve heard to counteract poor fuel efficiency. It seems Nissan is working on a gas pedal that will push back if a driver tries to “floor it” and accelerate too quickly. Rapid acceleration, of course, is a major drain on fuel economy, and Nissan says this system could up mileage by 5%-10% by calculating the most efficient rate of acceleration.
We have one major issue with this system: If you’re in a risky situation and need to accelerate quickly to avoid it, you’re out of luck.
However, Nissan says it will allow drivers to turn off the system manually.
