What? Plug-in hybrids don't need to plug in. It's just an option. It makes sense wether you have access to nightly charging or not. It's much better if you can charge, but the battery still helps you with efficiency by storing breaking energy, and the plug can also be used other places. Once plugins become more ubiquitous you'll probably start to see supermarkets and such offer charging in their parking lots. And it's really not that hard to add charging infrastructure to apartment parking. It's just a matter of will. The technology is simple and relatively cheap. You'll start to see companies offer owner of apartment complexes a pretty good deal: they'll install the chargers for free in exchange for them charging the tenants for the electricity (+ margins) This is a problem that be market is pretty good at solving if the government just gives its kick-start. Once plugins hits 20-30% market share (sales) it'll practically solve itself.
