Considering that production of conventional oil peaked in 2006 it is wise to look at alternate fuel/engine systems. Yes is $60k but will come down over the years as the investment pays off and volumes increase. Remember $10k plasmas?
I agree they're wise to "look at" but the point is more whether they're wise to purchase. I don't think any electric vehicle is a wise purchase yet (although it may be someday) since you're paying 40-60k for a car which is comparably equipped to a 20-30k car. The fuel saving is a nice touch but It doesn't come close to adding up. I'd easily buy a Corolla over a prius and pocket the difference
I think the Volt is the closes thing to a Viable alternative on the market right now. If your round trip to work is 50k's or so, you basically wouldn't use any fuel. But unlike full electric vehicles you can still have flexibility to drive further without looking for a powerpoint. The price is a downfall and it really needs cashed up environmental warriors looking for a warm and fuzzy feeling to start buying these like mad so They'll be affordable one day...
But even still plug in electric cars in Victoria and most of Aus rely on electricity produced from Coal. If 1M people came home from work on a Summer Arvo and plugged their cars in to charge our infrastructure wouldn't cope
So, its a step forward but very far from being viable in my opinion
