> PH = Plug-in hybrid (Same as a hybrid but you can charge up the hybrid battery at home)

You can, but in practice most people don't. And I can understand why -- it's inconvenient to have to plug in after every short trip, and the short electric range of most PHEV's means you do have to plug in after every short trip.

I plug in my EV around once a week, and it's more convenient than going to the gas station, but I'm not sure I'd want to have to plug it in every time I come home from even a short trip to the supermarket.

I plug in my EV almost every time I get home. The charger is hanging right next to my driver door in my driveway.

I own an EV. If I had a phev I'd sure love to plug it in rather than pay more for gas and have to go to the station.

That is why I setup our PHEV plug to be right next to the door, we park, grab the plug and put it in. That is at most 2 extra steps.
