Flower you seem to believe that a hospital provides a risk-free environment, although others have pointed out the ways in which a hospital can actually increase the risk of something going wrong. You don't seem to understand that everything in life is risky and you have to weigh up those risks in individual situations. Several people have pointed out that in some cases the journey to hospital is more dangerous than a planned home birth. You don't seem to understand that, simply because in your situation that wasn't the case.
There can be a risk involved in driving to hospital eg in adverse weather conditions or in the case of precipitous labour (you obviously don't understand this at all).
There can be a risk of overworked or negligent medical staff failing to recognize a problem that would be picked up by midwives in attendance at a home birth.
There is a risk of a medical emergency for mother or baby in a home birth that can't be dealt with in time.
It's not up to you to say that third risk is the only one that counts, particularly as you are so ill-informed about home birth and the situations in which they will transfer.
These risks will vary in each individual circumstance. It is up to each individual woman and the team of health care professionals with whom she is involved to assess these and make decisions accordingly. It is not up to you to decide you know the absolute risk for everyone else and to judge people as selfish for not agreeing with you.
Sometimes the wrong decision will be made. Sometimes there will be bad outcomes that could have been prevented. That's as true of hospitals as it is of other environments. There are never any guarantees.
