Regardless, today I wore my "bad" shoes and got out of the car without holding onto the door frame. I, uh, dragged my knuckles across the parking garage floor, and when I touched my car there was no shock. Pretty good! However, I tried the same in my home's garage, which has metal rods in the concrete. When I dragged my knuckles across THAT floor, I got a shock.
