Ouch. I don't have any experience driving a 370Z in snow, but it can't be that much different from driving my 240SX in the same situation. I would just leave it and find another way home or wait it out. Both choices do not include driving your RWD baby. You may be an excellent driver, but you should be more worried about the other folks (I usually use other words to describe them) on the road. Good luck.
Rob
