Depends on what people think. But I think the best post on the subject so far is your post with the graph showing a 22% improvement regardless of weight on the EPA cycle. Everyone here can beat EPA by doing a little DWB and anticipation, so expect an ecodriver to get <22%. Maybe 10%?
Edison2 has obviously determined that the weight penalty for making their VLC a hybrid erases their fuel savings.
DIY EV'ers may find that for the $ cost of going AC, they could instead buy more batteries to achieve greater range.
Folks who buy one-ton or heavier vehicles will probably say regen is well worth it, because it's a real boon on hills, and it's the best way to keep a hybrid's 12V battery charged.
