Fear of going into labour and not getting to the hospital in time

I live an hour away from the hospital, my mom will drive me there more then likely as my SO works away during the week. He will then meet us there. In a couple weekends he wants me to come stay with him (at his brothers) where he stays during the week as he’s working. Which is fine except

A. He works the Friday and I’ll be at the house with his two kids from his previous marriage.

B. He works 40 min from the house and the hospital is an hour and a half

C. Last time I was in labour it was only 5-6 hours with my angel baby.

At first I agreed to go but after thinking and realizing it’s only 1 week before my due date I’m not so sure... thoughts?
