An accelerator pedal assembly including an accelerator pedal attached to the driver's compartment of a vehicle is disclosed. The accelerator is reversibly movable between the neutral or idling position when no pressure is applied to the pedal and an acceleration position when pressure is applied. The assembly includes a compression assembly having a compression chamber with a piston, liquid nanofoam in the chamber, and a geared driver assembly connecting the compression assembly and the pedal. When the pedal is depressed, the driver assembly is activated, forcing the piston into the chamber and causing the force level to rise until it reaches the designed load limit or the threshold. When the pressure on the pedal is relieved, the position of the pedal is immediately reset to the neutral position as the piston is pushed out of the chamber by internal pressure generated by liquid escaping the nanoporous material via the nanopores.
