living without a car--is it possible?

well, today i called AAA and had them come out and jump-start my car....i am not planning on driving it--still haven't reinstated the insurance--but just in case, i have it at my disposal and can call my friendly state farm agent and say "ACTIVATE ME NOW"...i guess this is an unfair crutch to have, not a real rock-solid commitment to a car-free existence, but also, i can't just let the car sit in the garage and fester, can i? i need to keep it running just to keep the oil moving and the seals lubricated, non?
