^ Just consider the speed limit sign to have a typo, then.
As far as switching cars, we're talking about a huge cultural change. Granted that may be coming, but I can't see it that fast. Where are the old cars going to go? Just roll the problem down hill to the next poorer person? Send them to Bhutan? The process of recycling all our Excursions into EV1s will not come easy. In the meantime, while working toward that, we can make the best of what we have.
Besides, what's the Honda line? "Respect the van. Many of today's families started in one."
Also, while I don't have any figures to support a conclusion, it seems to me the embodied energy in producing a new FE car would take a while to be recovered in fuel savings. I can't say how long, though, with 50mpg difference.
