Regular hybrid vehicles still leave the owner 100% addicted to gasoline. That there's an electrical motor is barely significant to the fact that, for every mile the car moves, the energy required comes from gasoline. A plug-in hybrid electric vehicle gives the car owner the ability to have some of their miles come from a source other than gasoline. Of course a pure electric car gives total freedom from gasoline, but at the moment pure electric cars are hard to find. It's far easier to find a hybrid vehicle, but plug-in hybrid vehicles are not being made (today) by the car makers.
