If you happen to live on a hill and drive a stick, you could push start it... *may have in fact done this with a car with a wonky battery connection for like, three months one time, parking on a slope both at home and at work*

Also, ick. I am currently sharing one car with the husband and there is transporting of children and it is a giant pain in the ass to schedule the car and cope with Times Of Not Having It. Blech.
