well your options include...
snow socks, potentially crash into a kerb or some such?
snow chains, guess they could do damage if used incorrectly and then still the chance of sliding off somewhere
tow from another car, i wouldn't do it but then im too precious about the car
leave it where it is, is it that bad?
grit the road yourself and chip away at the ice and snow like a miner striking a vein of gold!
