Cathy- awesomesauce! That's fantastic!
driving- I live 30 minutes outside the nearest town and have three young kiddos, so we do a lot of local-ish driving no matter what. It's just not possible to avoid 4 or even 5 trips into town and back in a normal week. Personally I hate driving. I have an actual phobia about it and have had therapy, though it's still something that gives me regular panic attacks and general stress. (so yeah, ask why I agreed to move outside of town? no clue. big regrets. sigh). And the midwife/ob team I see and the hospital I'll use are both 45-60 minutes away.
However, I don't have any "extra" fear based on pregnancy. If I'm driving out of town (say more than an hour or two from home), and I'm close to full term or AM full term then I might google map the fastest route back to my hospital, or check out the addys for hospitals in that region but I don't worry about it too much. I think that as long as you are physically and emotionally comfortable driving, then you'll be fine. Maybe keep a hospital bag in the car and print out a "what to do in a surprise birth" list once you're close to/at term? And check with your care provider to see if they have any thoughts on the matter?
