How to get to the hospital without a car?

I'm due tomorrow Feb 18th hubby and I don't have a license at the moment just a learners permit. My sister was going to bring us home from the hospital since she has a car seat we can borrow but something came up with her job so she might not be able to come. I'm stressing about what to if the baby does come tomorrow BTW I'm a mom to be.

Forget to add that the hospital I'm registered at is an 8 min drive
