We've got cabs where I am that won't take a woman in labour, because amniotic fluid rots car seats if it gets on them, so their cab is buggered if the waters go while she is in transit. I think it's a BIG waste of everyone's time going in an ambulance though. We thankfully get very few where I am, but I think some years ago it was what you were supposed to do, call an ambulance. My mum certainly went to hospital in an ambulance with us lot. But then she probably didn't get told any different. People should just stay at home and have babies and it would be a whole lot simpler ;)
