Him - That cant be how it works.
ok i think i found the simplest example maybe....
electrons(static) are like heat... there not created or lost, but transfered. when you rub agains something with for example wool. the friction and material causess a build up of electrons on the wool. The wool is now charged with electrons. And anything that has less of a charge, the electron buildup on the wool will be atracted to it if its a good enough conductor.
and so a computer case will be zapped when you touch it untill the electron(static) charge between you and the case is equalized. The more electrons that grabbed on your cloths the higher the charge or greater the voltage will be. Its a quick shock though so its not like a sustaind current, but with that many volts the electrons obliterate the internals of some electric components by prolly putting electron holes threw them.
-----------------------------------------
I would guess that you could probably build up a high enough static charge to kill a person, but most likely will not happen because the electricity has to pass threw vital organs, but what it does is it just travels down the side of your body to ground.
-------------------------------------
and i may be rong, but i think it migh be .01a that is dangerous, not .1 ...... becuase all i remember is above 30v is dangerous, and dry human skin resistance is very high, so 30/.01 = 3000ohms
-------------------------------
and i dont know the exact reason why, but your safe in a car, not because the metal absorbes all the electricity. but either because the metal passes the electricy past you to ground, or the rubber gap between the car and ground is greater resistence then the surrounding tall objects around the car.

so, sorry him. i had to clear up your clear up post.
