Does anyone know if there's a kit available that would use the same principle as the Honda foot warmer? Has anyone tackled a homemade design for something like this? It sure seems like a shame to me that Honda couldn't have made this standard on all models or at least made simple, inexpensive parts available to add this option. Seems to me that an aftermarket designer and company could create such an add-on without too much brain strain or expense and make a handsome profit.
