Thanks.

Same reason you do it on a boat (and there are regs for boats but I don't think there are for cars!). If you have a build up of static electricity, from the gas flowing in to the tank, and you don't have a path from the tank filler to the ground circuit of the car, and the stars align properly, then you can get a nasty spark, which you don't want. The general rule for boats is that a metal fuel fill system and metal fuel tank have to have less than 1 ohm resistance to the system ground. But, if you're feeling lucky, feel free to disregard this.
