But... I think it has something to do with the static you build up while or sitting in the car. Cloth/carpet is a good source to charge the body up and when you touch something (metal/human) it causes an "electric shock". This or you're a damn mutant. Therefore I suggest hiding your identity so the government doesn't find out.
IT depends on what kind of answer you seek. Your answer is basically useless. If OP wants to actually get into properties of metals and atomic orbitals, then he might want that answer and that requires some reading; not just "static builds up because the carpet charges you and you get electric shocked."
