> I understand what the OP is saying.

You understand what OP would be saying if most of Europe had gasoline for $3.50 a gallon. Put in $2/liter instead and the crossover goes from 29MPG to 62MPG.

well, that's what the input boxes are for :) I don't know what the electric OR or gas rate is for wherever that person lives. But I think even your example of $2/liter, is a good thing for folks to internalize: the extremely high gas prices in europe, AFTER a worldwide systemic shock, at $7.57/gallon is break-even with a Prius at 56MPG at German/Italian prices of $.4/kwhr. Electricity is expensive, and at least in my state, I'm not seeing a serious commitment to doing something about it.
