What would a Hasidic person do if they were in a position where they had to drive (or get in a vehicle) on their Sabbath?

I was recently in the hospital for several days (voluntary surgery, if you’re wondering) and I was in a room with a Hasidic woman in the next bed. We got to talking and had some very nice conversations. She was supposed to be discharged on a Saturday but the doctor came in and said she could go home on Friday. She called her husband and he came with their kids and took her home.

I know that Hasidic people are very strict about their sabbath, and not driving or being in a car from Friday at sundown to Saturday at sundown. What would have happened if the woman were to be discharged home on Saturday? Her insurance probably would not pay for her to stay till Sunday. She was too far from home to walk (over a bridge, etc.).
