either someone was smoking, or someone induced an electric shock while pumping gas! lets hope the fault isn't a hybrid system inducing a spark or something
but suprisingly no one died just injuried, hope they get well!
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 195,000 km to date.
