The only point of a so called self-charging hybrid is to get better fuel economy (at quite a price) by using regenerative braking rather than brake pads. This is quite noticeable, but as said, the are totally fuel powered. A plug-in hybrid makes a bit more sense for people who do short trips most days and long trips occasionally. This is my situation; I have my Leaf now, I didn't get the longest-range model and I'll see how I get on with good planning. People who drive high mileages on time-critical business need the longest range car possible. At the moment this pretty much means a Tesla, but the scene will be very different in a year or two. Caravanners and trailer haulers will have to wait a bit too.
