TS this has nothing to do with the car, your body has high static currents & discharging it to the car instead. (metal parts)
Read more about it under health section:
http://forum.lowyat.net/index.php?showtopic=488752&hl=http://www.static-sol.com/articles/static_shocks.htmStatic discharge & electric discharge are different:
Static discharge wll give out a spark only once, through human body to any metal parts or from human to human.
Electric discharge stays on the metal or glass surface whenever electricity is turned ON (AC/DC) . You can use a test pen to check. Most probably the item is not grounded properly.
I always get static discharge in my office door knob & cubicle.
Last time I had an electric shock on my CRT glass monitor & a metal cover on my home amplifier.
True and maybe not true.
In the car, since our bodies are rubbing with the seat etc then electrostatic will buildup and discharge when we touch metal when exiting car.
But, our moving vehicle will generate electrostatic when it 'rub' with air or tyres friction with road - it's dangerous, that why fuel tanker use metal or rubber strap to ground/discharge them.
Personal experience, I still get shocked from electrostatic charge sometime when exiting. FYI, I am as driver I am sure I am electrostaticly clean as I turn off the ignition key (my key is bare metal)
... after reading this so tempted to buy an antistatic grounding strap. I am sure they are useful, the tanker has it, rally car has it - I don't think the factory machine will put it on if not useful. Maybe the misty fan at petrol station also has its logic?... dry air sparks?
