Another S owner who wishes that cruise control, a $10 upgrade, was not held ransom to a multi-thousand dollar upgrade package. A vehicle as silent as the Leaf really benefits from cruise for any sort of routine operation on uncrowded freeways, even in the base model.
Will be interested in retrofit possibilities. It does appear simple, in concept, to add the switch panel. Kind of a surprise that they spec'd a separate spiral cable for the S. My money says they disabled that software module in the VCM, but I'd be happy to be proven wrong.
