Hybrid-Car Tinkerers Scoff at No-Plug-In Rule

The whole point of a Hybrid is that you don't have to plug it in and it makes its own electricity, if you want a car you can plug in, get an electric car. What the fuck is wrong with people. And anyway, if you have to plug it in, doesn't that negate some of the benefit, since you'll then be paying for the electricity, not to mention other resources are being used to make that electricity? I'm probably missing something, but I don't get what the benefits are, or at least not how they would outweigh the drawbacks.
