1. A brake pedal feedback system, comprising:
a spring driver including a first recess and a second recess;
a first spring connected to the spring driver;
a first brake pedal including a first extension at least partially positioned in the first recess; and
a second brake pedal including a second extension at least partially positioned in the second recess;
when the first brake pedal is in a disengaged position and the second brake pedal is in a disengaged position, the first extension is spaced apart from a first surface of the first recess, the second extension is spaced apart from a first surface of the second recess, and the first spring is in a relaxed condition; and
when the first brake pedal is in an engaged position and the second brake pedal is in the disengaged position, the first extension contacts the first surface of the first recess causing the spring driver to move the first spring from the relaxed condition to an energy storing condition.
