The energy in the building of the car is a sunken energy cost as you 
already own it and would regardless. The same may be said in a slightly 
different way about the food comsumption of an "average" person versus a 
vegan. The point is moot, though interesting, as your not about to 
change your food consumption to save energy. In fact your more likely to 
exercise so that you can eat more of what you want. In which case as 
this is a sunken energy cost you might as well derive some value out of 
it by producing useful energy instead of it going into a heat sink 
(friction, resistor, etc).

yeah, enough to drive you insane. Hang on, isn't that what the day job 
is for ;-).
