If one of the drivers has difficulty reaching the accelerator pedal, look into having a left-foot pedal installed. These are available at stores specializing in adaptive equipment for the disabled. Many of these companies can also install it for you or direct you to centers that specialize in this type of equipment.
The left-foot accelerator pedal is closer to the driver’s seat and often ends up approximately the same relative distance from the seat as the brake pedal. Therefore, the left pedal is a bit more accessible to the driver with shorter legs.
Sure, it will take some effort to become comfortable but worth it in the long run for driving comfort and safety. Remember, before heading out on a road trip with the newly-installed left-pedal drive, practice using it in a large, empty parking lot or lonely, private road.
The left-foot accelerator pedal folds flat on the floor when the next driver takes over. It is used in the “up” position when it is simply “resting on” and not permanently fastened to the normal, right-foot accelerator pedal.
