The evidence on that one is anecdotal but as anecdotal stuff goes it’s exceptionally good. I have relatives who buy and sell cars for a living, wholesalers who work with the big East Coast auctions in Fredericksburg Va. and Manheim Pa. and the mechanics who work with them are telling us these stories, i.e. that they’re getting so many of the Prius’s and hybrid Civics in at 100K for battery grief and the economics of the thing as I mentioned are so bad, that you’re correct in saying that the basic life-span of one of them is around 100K miles.
I would rather live in five minutes in a world comprised of your anecdotal evidence than an eternity in Obamaworld.
