If you did go by car it would have to be a very smooth & stress free driver...

smooth roomy comfortable car
lots of extra pillows for propping and padding
maybe even a note for no seatbelt use ?? not sure how others did that part - last thing you need is a jerk or pressure on the area

plane might be best...

hospital shuttle ride to airport perhaps?
but hopefully someone would be with you at that time too?

I can't remember how soon some of the others flew or "drove" home after their surgery.
