Well on a run, how many times do you FAS? I mean the car wasn't designed to turn off and on consistently unless your telling me it's okay!? I don't get the science behind it, how many "cranks " can a starter go for before giving up? How about the 12 volt battery, aren't you abusing that too? I thought turning the engine off and on is bad for the engine too (I mean isn't that why idling exists?) At least I understand the prius revs the engine to a certain RPM before allowing fuel to be injected into the cylinders.

but a normal car doesn't have that kind of luxury

i got around 20 km a liter when i drove a civic 5 spd using advanced hypermiler techniques
and now I drive a salvage nwh20 prius that gets almost to 25 km/l with 192,000 km to date.
