John,
{trying to be dispassionate here} Perhaps you might want to define your terms - P&G, FAS, etc. If you want to describe P&G on an HSD, go for it - it would be helpful to the requestor. My definition of Pulse and Glide is not restricted to any type of vehicle, as it's been used since the 1930's or 1940's

Pro’s include maximizing FE in a low speed suburban or city environment (speed limits less then 45 mph). Con’s include lowering your overall average speed (more time to get to point B), a lot of work given the undulations depending on the type of hybrid or non-hybrid you are driving, and both gear reduction starter and pre-mature transmission wear from re-engagements at speed depending on the automobile being analyzed. |
