I'm sure there are horror stories galore about zapping ICs, but it has never happened to me. I don't shuffle across the carpet and reach out my finger to touch the metal pins, but I don't even own a wrist strap.
I will frequently touch a metal edge before I touch components. That's about the extent of it.
Perhaps by the time I've soldered my 100,000th joint, I'll have a negative experience (other than burning myself or inadvertently melting something plastic, that is).
but, sorting parts in the car? That's just asking for lost pieces. Never mind the static.
