How soon can you drive?

How soon after you give birth can you drive? Obviously not the day you leave the hospital but to like the first dr appointment? My grandma would be the only one who could drive me and her car smells like cigarettes and I don’t want my newborn breathing that in. I literally just got this brand new car a month ago and don’t trust anyone else to drive it besides my cousin who is taking me and my baby home in it because he’s drivin it before but he will most likely be at work or busy to take us to the dr. I hate having people drive me around so it’s going to annoy me 🙄
