In the states, priuses are being converted to a 9kwh battery pack, this
gives the equivalent cost per mile of 180 mpg till it runs out (about 40
miles at sub 40 mph) then the standard system comes back in and you get
50 mpg , or of course if you need more than 40 mph it is available from
the start. http://www.calcars.org/ However, lots of commutes are sub 20
miles each way on congested roads, so the conversion must be very nice
to have.

This '180 mpg' depends on using untaxed domestic electricity to charge the
battery and comparing the cost to that of taxed petrol. However, if you
run a diesel on free old chip oil you might get 1000 mpg + using the same
flawed comparison.

Knock on the neighbours door and ask them for chip oil because you are going
to work? Wow!
